Full textAbstract:
Recycled post-consumer high-density polyethylene pipe plastic was agglomerated into composite samples with wood, glass fiber, mineral wool, gypsum, and soapstone as recycled particulate fillers. The tensile strength, tensile modulus, impact strength, and hardness were the mechanical properties evaluated. Scanning electron microscopy was performed on the broken surfaces of tensile strength samples to study the interfacial interactions between the composite matrix and the filler materials. Heat build-up, water absorption, and thickness swelling were the physical properties measured from the composites. The addition of particulate fillers demonstrated the weakening of the tensile and impact strength but significantly improved the rigidity of the post-consumer plastic. The composites filled with minerals had mechanical properties comparable to compression molded wood plastic composites but higher resistance to moisture. A lack of hot-melt mixing affected the mechanical properties adversely.

The potential utilization of melamine impregnated paper (MIP) waste in thermoplastic composites was investigated. Composites were also manufactured utilizing wood flour (WF) at the same filler rates for comparison. The composites were manufactured using a compression molding method. The effects of filler type and filler rate on the mechanical properties of low-density polyethylene (LDPE)-based composites were evaluated. Mechanical properties, such as tensile and flexural strengths, were determined in accordance with ASTM D638 (2001) and ASTM D790 (2003), respectively. Results showed that filler type and filler content had significant effects on all mechanical properties investigated. Both fillers improved all mechanical properties except for tensile strength and elongation at break of LDPE. In conclusion, MIP waste has a potential to be utilized in thermoplastic-based composite manufacturing and might generate some economic and environmental benefits.

Abstract Plastic lumber and thermoplastic composites are sold as alternatives to wood products. However, many technical standards and scientific studies state that the two materials cannot be considered to have the same structural behaviour and strength. Moreover, there are many compositions of thermoplastic-based products and plenty of wood species. How different are their mechanical properties? This study compares the modulus of elasticity and the flexural, compressive, tensile and shear strengths of such materials, as well as the materials' specific mechanical properties. It analyses the properties of wood from the coniferae and dicotyledon species and those of commercialized and experimental thermoplastic-based product formulations. The data were collected from books, scientific papers and manufacturers' websites and technical data sheets, and subsequently compiled and presented in Ashby plots and bar graphs. The high values of the compressive strength and specific compressive and tensile strengths perpendicular to the grain (width direction) shown by the experimental thermoplastic composites compared to wood reveal their great potential for use in compressed elements and in functions where components are compressed or tensioned perpendicularly to the grain. However, the low specific flexural modulus and high density of thermoplastic materials limit their usage in certain civil engineering and building applications.

In order to make high performance wood-plastic composites (WPCs) from wood-fiber and mixed plastic wastes, virgin resins were compounded to simulate mixed plastic wastes, which included polypropylene, polyethylene and/or polystyrene, then grafted with maleic anhydride (MAH) by reactive extrusion. Highly filled WPCs were prepared by extruding. Mechanical testing results showed that the mechanical properties of the composites based on grafted virgin and waste plastics both significantly enhanced. The compatibility between the different plastics in the blend system and the interfacial adhesion between wood fibers and the blends were both improved with the modification of the blends, as evidenced by SEM. For the composites based on MAH grafted plastics, the water absorption and thickness swell decreased, which is true for the composite made from both virgin and recycled plastics. This blending-grafting modification method can be considered as a feasible approach to use mixed plastic wastes in the manufacture of high performance WPCs.

Abstract Chemically modified wood composites were obtained via the compression moulding of thermoplasticised Aspen (Populus tremula) sawdust. This sawdust was previously prepared by esterification with maleic anhydride (MA) and subsequent oligoesterification with maleic anhydride and glycidyl methacrylate (GMA). The thermoplastic properties of the chemically modified wood resulting from different modification procedures were confirmed and compared by compression-moulding experiments leading to preliminary and final products. An SEM study of the resulting products clearly showed that the oligoesterified wood had partially melted under pressure and temperature, such that the overlapping and surface melting of particles ensured adhesive bonding between those particles. A new type of wood/thermoplastic-wood composite was obtained. In these composites, the melted part of the modified wood plays the role of the cohesive matrix whilst none-melted wood remains as a fibrous reinforcing material. FTIR spectra suggested that changes in the chemical structure of the modified wood are possible during the thermal forming process (e.g. polymerisation of C=C double bonds). The final composites were yellowish-brown, glossy, plastic-like products that showed interesting physical, mechanical and biological properties. They are water-resistant and dimensionally stable and display good electrical insulating behaviour. Their mechanical properties (bending strength of ca. 64 MPa and tensile strength of ca. 36 MPa) are in the typical range for plastics and conventional wood-fibre/plastic composites, and are superior to common wood products such as fibreboards and particleboards. Furthermore, the outstandingly high internal bond (ca. 3.0 MPa) highlights the totally different adhesion mechanism operating in these new types of composites. Although the novel composites are much more resistant to decay than the original unmodified wood, they remain ultimately biodegradable plastic-like composites.

In this article, wood-plastic composites(WPCs) were manufactured with wood flour(80～120mesh、40～80mesh、20～40mesh、10～20mesh) combing with high density polyethylene(HDPE). Effects of the size of wood flour on mechanical properies and density of composites were investigated. Results showed that particle size of wood flour had an important effect on properitiesof WPCs. Change of mesh number had a outstanding effect on flexural modulus, tensile modulus and impact strength, howere, little effect on flexural strength and tensile strength. When mesh number of wood flour changed from 80～120mesh to 10～20mesh,flexural modulus and tensile modulus were respectively enhanced by 42.4% and 28.4%, respectively, and impact strength was decreased by 35.5%.Size of wood flour basically had no effect on density of composite within 10～120mesh. The use of wood flour or fiber as fillers and reinforcements in thermoplastics has been gaining acceptance in commodity plastics applications in the past few years. WPCs are currently experiencing a dramatic increase in use. Most of them are used to produce window/door profiles,decking,railing,ang siding. Wood thermoplastic composites are manufactured by dispering wood fiber or wood flour(WF) into molten plastics to form composite materials by processing techniques such as extrusion,themoforming, and compression or injection molding[1]. WPCs have such advantages[2]：(1)With wood as filler can improve heat resistance and strength of plastic, and wood has a low cost, comparing with inorganic filler, wood has a low density. Wood as strengthen material has a great potential in improving tensile strength and flexural modulus[3]；(2) For composite of same volume, composites with wood as filler have a little abrasion for equipment and can be regenerated；(3)They have a low water absorption and low hygroscopic property, They are not in need of protective waterproof paint, at the same time, composite can be dyed and painted for them own needs；(4)They are superior to wood in resistantnce to crack、leaf mold and termite aspects, composites are the same biodegradation as wood；(5)They can be processed or connected like wood；（6）They can be processed into a lots of complicated shape product by means of extrusion or molding and so on, meanwhile, they have high-efficiency raw material conversion and itself recycle utilization[4]. While there are many sucesses to report in WPCs, there are still some issues that need to be addressed before this technology will reach its full potential. This technology involves two different types of materials: one hygroscopic(biomass) and one hydrophobic(plastic), so there are issues of phase separation and compatibilization[5]. In this paper, Effects of the size of wood powder on mechanical properties of WPCs were studied.

Abstract Wood plastic composites (WPCs) are typically composed of wood particles, thermoplastic polymers and small amounts of additives. Further improvement of WPC technology requires a better understanding of their mechanical performance and durability on the micro level. X-ray computed tomography (CT) and advanced imaging techniques can provide visualization and support characterization of the internal structure, deformation and damage accumulation in WPCs under loading and various environmental exposures. However, both wood and thermoplastics are weakly attenuating materials for X-ray and good contrast between these two components is difficult to obtain. In the present study, chemically inert gold nano-particles and micro-particles were investigated as contrast agents to improve X-ray CT scanning contrast between wood and thermoplastics. The effect of adding 1% (by wt.) gold nano- and micro-particles on the tensile properties of wood/high-density polyethylene composites was addressed. Samples with and without surfactant were tested in tension and scanned on a custom desktop X-ray CT system. It was found that the addition of gold particles did not impair the WPC tensile properties. However, some of the tensile properties were significantly affected if the surfactant was included. Gold micro-particles were shown to disperse well without surfactant and significantly improve the X-ray CT scanning contrast between wood and polymer, while gold nano-particles (without surfactant) did not disperse well and do not contribute to contrast improvement.

This review deals with recent works on the process and technological aspects of wood-plastic composites (WPCs) manufacturing.WPCs relate to any composites that are built from wood and non-wood fibers and thermoplastic polymers. Recent progress relevant to wood-plastic composites has been reviewed in this article. The process and technological aspects of WPC, such as raw materials, fabrication, mechanical, physical, thermal, and morphological properties, were outlined comprehensively. The manufacturing process of WPCs is an important aspect of WPCs production. Manufacturing methods like compression molding and pultrusion have some limitations. Extrusion and injection molding processes are the most widely used in WPCs due to their effectiveness. Recent developments dealing with WPCs and the use of different kinds of nanofillers in WPCs have also been presented and discussed. Nanoclays are widely used as nanofillers in WPCs because they represent an eco-friendly, readily available in large quantity, and inexpensive filler. WPCs can be found in a wide range of applications from construction to the automotive industry.Keywords: additive manufacturing, adhesion, fabrication techniques, mechanical and physical properties, wood-plastic composites

Full textAbstract:
Novel Kraft fiber reinforced unsaturated polyester (UPE) composites were prepared at various molding pressures in order to investigate the effects of molding pressure on resin content, the mechanical properties and creep resistance. The results indicated that the novel composites had much higher mechanical properties and better creep resistances than traditional wood plastic composites because of the applications of strong Kraft fibers as reinforcement and thermosetting UPE as matrix. Molding pressure had various effects on the many properties of composites. With molding pressure increased from 6MPa to 25MPa, the mechanical properties and creep resistances increased gradually until about 20MPa and then decreased, which were attributed to the different interface adhesions between UPE resin and Kraft fibers at various molding pressures as evidenced by DMA analysis. Benefited from the use of low-viscosity UPE resin, the resin content of Kraft fiber reinforced UPE composites could reduce to 28.3% while strength and creep resistance were still much better than that of the thermoplastic wood-plastic composite (WPC) with 40% polymer matrix.

Traditional medical external fixation material represented by gypsum is brittle, heavy and prone to adverse reactions, clinical effect is not ideal. The pine wood fiber particles (size for 10 ~ 40 mesh) and polycaprolactone (PCL) are used to prepare a new kind of wood-plastic polycaprolactone composites (WPC) by the blending method. The experimental results show that the increase of PCL mass ratio can enhance the material strength and flexibility, especially the match force between the pine wood fiber particles. Meanwhile, when the mass ratio of PCL reached 65%, this enhancement effect significantly diminished; after the mass ratio of PCL reached 70%, the phenomenon of material mechanics performance decline. In this paper, the prepared WPC, which can soften under temperature 50°Cand repetitively finalize the design, have good mechanical properties, low-temperature thermoplastic and environment protection.

The application-oriented distribution of wood chips is a major obstacle in the production of 3D molded composite parts made of plastics and wood. Similar to fibers in conventional fiber-reinforced plastic components long chips can be used for force transmission. Short chips and wood powder can be distributed homogeneously between longer chips to increase the wood volume percentage and to allow post-processing-free edge areas. The applied process parameters during the incorporation of the matrix material determine the filling of the cavity and the impregnation of the chips. Different formaldehyde-free resin and adhesive systems, as well as thermoplastic powders are used as matrix material. By controlling the subsequent pressing process of the oriented and impregnated chips the density and wall thickness of the molded part can be influenced. In this work different production process variants and a concept for a modular 3D experimental mold are investigated. The flowability and bulk density of the wood chip fractions are characterized and the compression pressure required in the production process is determined. Initial tests with a panel mold are carried out and the bending strength of the manufactured specimen is examined.

The effect of cotton dust as filler on the mechanical and thermal properties of polypropylene composites was investigated and the results were compared with the properties of wood plastic composites. Cotton dust was obtained from the dust filtration system located in a textile manufacturing unit. Different mixtures of cotton dust (30 to 60 wt%) or wood flour (30 to 60 wt%) were compounded with polypropylene with a coupling agent (maleic anhydride grafted polypropylene 3 wt%) in a twin-screw co-rotating extruder. The test specimens were produced by injection molding machine. The tensile strength and flexural modulus of the specimens improved with the increase in the filler content. There was no significant difference in the strength and modulus values between the cotton dust and wood flour filled composites. The highest thermal stability was found to be in the composites produced with 40 wt% of cotton dust according to the results of differential scanning calorimetry analysis. Based on the findings obtained from the present study, the optimum mechanical and thermal properties for the filled polypropylene composites were found to be a 50/50/3 formulation of cotton dust, polypropylene, and maleic anhydride grafted polypropylene, respectively.

Relative lower strength and poor creep resistance of wood-plastic composites (WPC) restrain their wider applications in building and automotive. A novel wood-polymer composite was prepared using Kraft fiber and unsaturated polyester (UPE), which had much higher strength and better creep resistances than that of traditional thermoplastic WPC. Effects of initiator on the mechanical properties and creep resistance of this novel composite were investigated by tensile evaluation, DMA, SEM and short-term creep test. Test results indicated that initiator level had important effects on mechanical properties and viscoelastic behaviors because of various crosslinking densities of UPE matrix and interface adhesions between Kraft fiber and UPE resin under various initiator levels. With initiator level increased from 0.3% to 1%, the tensile strength and interface adhesion increased at the beginning and then decreased, while the instantaneous strain and maximum strain in the creep test decreased gradually. As for hot molding at 125°C, initiator level shall be less more than 1% and be preferable to 0.5%-0.7%.

Effects of adding small amounts of cellulose nanofibers and nanoclay particles on physical and morphological properties of biodegradable composites made of starch thermoplastic polymer and industrial sawdust were investigated. For this purpose, these nanoparticles were mixed with wood plastic composites (WPCs) at 0%, 3%, and 5% weight percent. Water absorption, thickness swelling, thermal dynamic mechanical tests, and also degradation tests were performed according to corresponding standard test methods. The results showed that adding small amounts of cellulose nanofibers and nanoclay particles can be successfully used as filler and improve overall performance of the above-mentioned WPCs.

Glass fibre is the most widely used material for reinforcing thermoplastic matrices presently and its use continues to grow. A significant disadvantage of glass fibre, however, is its impact on the environment, in particular, due to the fact that glass fibre-reinforced composite materials are difficult to recycle. Polyamide 6 is an engineering plastic frequently used as a matrix for high-mechanical performance composites. Producing polyamide monomer requires the use of a large amount of energy and can also pose harmful environmental impacts. Consequently, glass fibre-reinforced Polyamide 6 composites cannot be considered environmentally friendly. In this work, we assessed the performance of a road cycling pedal body consisting of a composite of natural Polyamide 11 reinforced with lignocellulosic fibres from stone-ground wood, as an alternative to the conventional glass fibre-reinforced Polyamide 6 composite (the most common material used for recreational purposes). We developed a 3D model of a pedal with a geometry based on a combination of two existing commercial choices and used it to perform three finite-element tests in order to assess its strength under highly demanding static and cyclic conditions. A supplementary life cycle analysis of the pedal was also performed to determine the ecological impact. Based on the results of the simulation tests, the pedal is considered to be mechanically viable and has a significantly lower environmental impact than fully synthetic composites.

Eco-friendly composites are proposed to substitute commonly available polymers. Currently, wood–plastic composites and natural fiber-reinforced composites are gaining growing recognition in the industry, being mostly on the thermoplastic matrix. However, little data are available about the possibility of producing biocomposites on a silicone matrix. This study focused on assessing selected organic fillers’ impact (ground coffee waste (GCW), walnut shell (WS), brewers’ spent grains (BSG), pistachio shell (PS), and chestnut (CH)) on the physicochemical and mechanical properties of silicone-based materials. Density, hardness, rebound resilience, and static tensile strength of the obtained composites were tested, as well as the effect of accelerated aging under artificial seawater conditions. The results revealed changes in the material’s properties (minimal density changes, hardness variation, overall decreasing resilience, and decreased tensile strength properties). The aging test revealed certain bioactivities of the obtained composites. The degree of material degradation was assessed on the basis of the strength characteristics and visual observation. The investigation carried out indicated the impact of the filler’s type, chemical composition, and grain size on the obtained materials’ properties and shed light on the possibility of acquiring ecological silicone-based materials.

Rotomolding is a versatile process used in the manufacture of thermoplastic polymeric materials to produce large hollow plastic parts. The aim of this review article was to discuss the rotomolding process and show the properties of the polyethylene composite and rotomolded lignocellulosic fibers, which are processed for prolonged periods under temperature. The main process parameters studied are the shaft speed of the equipment, molding temperature, polymer particle size, polymer melt flow index, and amount of material, which must be well controlled to achieve a non-degraded product with homogeneous thickness and no porosity. Rotomolded composites containing sisal, pine, coir, banana, flax, and maple wood fibers, among others, have been evaluated primarily for their mechanical (impact, flexural, and tensile strength) and morphological properties. The type, content, and treatment of lignocellulosic fillers are the most widely studied variables in polyethylene-based rotomolded composites. Fiber content was the variable that most influenced mechanical properties, particularly impact strength and hardness due to the voids formed by the hydrodynamic volume between the polymer matrix and lignocellulosic filler. Chemical treatment of the fiber by mercerization with NaOH made it more hydrophobic and the addition of maleic anhydride-grafted polyethylene as a coupling agent improved the interfacial adhesion between the non-polar polymer matrix and polar filler. However, the best mechanical property results were obtained with the use of maleic anhydride-grafted polyethylene.

The potential of recycled wood flour (r-WF) addition to the thermoplastics polypropylene (PP) matrix for the composites in structural application is evaluated. The effects of different r-WF loading to the tensile and impact mechanical structural properties are analyzed. Two types of polypropylene resin which are the virgin and the recycled resin and recycled wood flour as reinforcement materials are utilized as raw materials in the composites fabrication. Various mechanical testing was conducted in accordance to ASTM standard, to study the behavior of the composites mechanical properties to the applied load. The best compounding formulation of enviro-recycled composite was found at 60wt% of PP matrix and 40wt% of the wood flour addition for both of virgin and recycle matrix. Overall experimental results showed that, the increasing of r-WF loading had significantly increased the mechanical properties of produced composite which is suitable to be applied in the application of structural engineering, through the advantage of mechanical properties performance in tensile and impact behavior. Conclusively, this finding is hoped to lead for contribution in the development of newly advanced material that is environmental friendly for the use of structural application.

The paper deals with destructive testing of �new� group of material - Wood Plastic Composite (in short WPC). WPC emerging from a fusion of two different kinds of components - thermoplastics matrix and natural reinforcement (fibres or flour). Natural fibres offer several advantages - they are renewable, inexpensive, low-density, good isolate a sound and low cost. These components are mixed under the influence of high temperature and then pressed to make various shapes. This material contains cracks localized on the interface between the wood and plastic. These cracks occurred due to inhomogeneity of WPC and affected mechanical properties of final WPC product. The testing of mechanical properties (tensile test and bending test) were determinate in VUHZ Dobra (Ostrava) - following the ISO standards. Significant differences between mechanical properties after testing were caused by non-perfect encapsulation between components and non-homogeneity of materials.

This study aims to develop a new wood-plastic composite (WPC) material from recycled thermoplasctics. The recycled low-density polyethylene (rLDPE) and high-density polyethylene (rHDPE) were used as matrix, whereas the diatomaceous earth waste (D) and wood fiber (WF) as filler. Recycled-LDPE and rHDPE were recovered and pelletized by a plastic recycling process. The 10-30wt.% diatomaceous earth waste was heat-treated at 200°C to remove impurities. The diatomaceous earth, maleic anhydride grafted polyethylene (MAPE), CaCO3, slip agent, antioxidants and WF were then mixed at 160°C, for 10 minutes, at stirring speed 50 rpm to produce wood-plastic composite material. The mechanical strength and thermal properties of the composites were investigated. The composite containing D and rLDPE results in an increase the hardness of the material which is higher than that of the virgin-LDPE. The tensile and impact strengths of the composite material prepared by rLDPE and D were higher than those of the rHDPE composite material. It is found that LDPE has excellent fluidity, which is helpful for subsequent processing. In addition, the diatomaceous earth waste can be used to reduce the cost of the raw material, and the product has both effects of environmental protection and marketability.

Polymer building materials are used as substitutes for materials such as brick, concrete, metal, wood and glass, and in addition to traditional materials. Plastic materials are light, can be formed into complex shapes, durable and low, and also possess a wide range of properties. Plastic materials are available in various forms, colors and textures and require minimal or no color. They are resistant to heat transfer and diffusion of moisture and do not suffer from metal corrosion or microbial attack. Polymeric materials, including thermoplastics, thermoset materials and wood-polymer composites, have many structural and non-structural applications in the construction industry. They provide unique and innovative solutions at a low cost, and their use is likely to grow in the future. A number of polymer composite materials form complex material compositions, which are applied in the construction in order to analyze the processes of damage accumulation under the conditions of complex nonstationary loading modes, and to determine the life of structural elements considering the material aging. This paper present the results of tests on short-term compression loading with a deformation rate of v = 2 mm/min using composite samples of various shapes and sizes.

Today, the technology of extrusion 3D printing of plastic products is developing at the highest rate, due to its availability. Therefore, the creation of composite materials, based on thermoplastics, which contain various additives, aimed at improving the physico-mechanical and aesthetic characteristics is becoming more important. In this regard, the studies on the effectiveness of using a thermally modified wood filler in the filaments, used in extrusion 3D printing technologies, were conducted in this work. It was found that the presence of a thermally modified wood filler reduces shrinkage of the composite and allows obtaining products with the smallest surface roughness. However, with a high content of filler in the composite, a decrease in its strength properties is observed.

Palm frond waste is a lignoselulose material that is abundant availability in Indonesia. The material has potential to be used as raw material for wood plastic composite material (WPC). The purpose of this reseach was to study the effect of levels of treated palm frond (TPF) and maleated polypropylene (MAPP) compatibilizer to the properties and morphology of the palm frond-based WPC. As thermoplastic component was used polypropylene (PP). Extractable components from palm fronds removed with water washing and drying. The WPC samples were prepared by mixing PP, TPF, MAPP and paraffin in the internal mixer at temperature of 170°C and rotor speed of 80 rpm for 15 minutes. The mass ratio of PP/TPF was varied with 50/50, 60/40 and 70/30 w/w. The MAPP levels was varied with 0%, 4% and 5% w/w. Paraffin was used as a palsticizer with a level of 2% w/w. The testing included tensile and flexural properties by using universal testing machine (UTM) according to ASTM D-678 and ASTM D-790 standards, respectively. Other testing also conducted for morphology by using scanning electron microscope (SEM) and water adsorption test. The result indicate that the best properties of the WPC sample obtained at PP/TPF mass ratio of 60/40 w/w and MAPP level of 5% w/w, with tensile strength of 156 kgf/cm2 and flexural strength of 598 kgf/cm2 with water adsorption of 1.4% w/w.

The secondary processing of WPC (wood-plastic composite, WPC) is a necessary method to make its productions more beautiful while it is applied in furniture, sanitary location, bathroom and other fields. Although there is widespread availability of WPC abroad, such as building, municipal installations, packing and other occasions, but on the contrary, there is little application in our country. As a substitutes of wood, WPC has many excellent performances such as light weight, high rigid, water resistance, insect resistance, acid and alkali resistance etc, it can be nailed, drilled, planed, sawed, agglutinated and painted like lumber. Furthermore, it can be extruded as thermoplastics, and decorated by printing or spraying. In this research, problems of WPC popularization in domestic furniture market are clarified by analyzing the material performances and consumer mentality.

Full textAbstract:
Fully impregnated fiber-reinforced thermoplastic sheets, or the so-called organic sheets, allow the thermoforming of parts within very short cycle times. This article describes the development of the next generation of organic sheet materials based on recycled carbon fibers and polyamide 6 staple fiber yarns. Regardless of the recycled nature of the fibers and an average fiber length of 25 mm, the organic sheets still reach a comparable level of the tensile strength and modulus of continuous fiber-reinforced organic sheets made of virgin CF with the same reinforcement structure. Due to the staple fiber yarn architecture, the organic sheets feature a deep-drawing ability of a total plastic deformation up to 50% in the fiber direction. The effect is enabled via an interfiber sliding when the organic sheet is processed in the molten condition. The creation of a finite element model for the thermoforming process simulation of the material is also presented. Predictions of the plastic strain distribution and its magnitude are shown to agree well with forming experiments where a curved geometry is formed to different depths.

Nowadays, natural fibre-thermoplastics composites (NFPC) are replacing the conventional wood and timber due to its lower cost, avoid deforestation, higher strength-to-weight ratio and resistant to termites. These composites can be utilized for non-structural components of a building system such as decking, wall cladding, floor tiles and window frame. A natural fiber/plastic composite was produced by extrusion molding process to create a wall cladding profile. The raw materials used for the composites are 40% kenaf fibre and 60% polypropylene (PP). These materials were compounded through a twin-screw extruder and then cut into pellets. The moisture content found in the kenaf/PP composites (KPC) pellets was 2.89%. Therefore, the pellets required to be oven dried every time right before entering the hopper of the extruder. The temperature along the barrel was set to 180°C and the die head temperature is set to 165°C. At the end of the extrusion molding process, pressurized air was used for cooling the profile. Then, samples of the wall cladding were taken back to the laboratory for product quality assurance. Measurements of the samples show that the product experiences 3% of shrinkage in term of width and 1% of shrinkage in term of thickness. Water absorption test indicates an increase of 13.6% of weight after 24 hours immersion of water. Impact strength test was also conducted on the wall cladding samples and the mean result was 2.55 kJ/m². Tensile test on the extruded KPC product indicates a low tensile strength at 4.51 MPa and tensile modulus of 205.01 MPa. The sample also proven to be light weight as the density of the material was found to be 0.618g/cm³.

A number of equations are available for predicting the output of machining processes. These equations are most commonly used for the prediction of surface roughness after tooling. Surface roughness can be influenced by many factors, including cutting parameters, tool geometry and environmental factors such as the coolant used. It is difficult to create a universally applicable equation for all machining because of the variations in different materials' behaviours (e.g. metal, wood, plastic, composite, ceramic). There are also many differences between the various types of machining process such as the machining tools, rotational or translational movements, cutting speeds, cutting methods, etc. The large number of parameters required would make such an equation unusable, and difficult to apply quickly. The goal is thus to create a simple formulation with three or four inputs to predict the final surface roughness of the machined part within adequate tolerances. The two main equations used for this purpose are the Bauer and Brammertz formulas, both of which need to be optimised for a given material. In this paper, the turning of thermoplastics was investigated, with the aim of tuning the Bauer formula for use with thermoplastics. Eleven different plastics were used to develop a material-dependent surface roughness equation. Only new tooling inserts were used to eliminate the effects of tool wear.

Em decorrência de preocupações ambientais, o desenvolvimento de novas tecnologias e materiais de alto desempenho vem sendo direcionado para o campo da sustentabilidade, com a utilização de recursos naturais e renováveis. Fibras vegetais estão sendo cada vez mais utilizadas como reforço em termoplásticos em virtude de seu baixo custo, altas propriedades específicas e natureza renovável. A adição de fibras naturais aos compostos poliméricos pode causar alteração nas suas propriedades, características e comportamento mecânico, por isso a necessidade de estudos que tratem da produção e caracterização destes materiais. O polipropileno (PP) modificado com anidrido maléico (PP-MAH) é o compatibilizante mais comumente utilizado para auxiliar na melhora da aderência interfacial entre as fibras de madeira (hidrofílicas) e o polipropileno (hidrofóbico). Sendo assim e, devido a versatilidade e aplicabilidade industrial dos compostos plásticos reforçados com fibras naturais, o objetivo do presente trabalho foi a produção de um compósito polimérico constituído PP reforçado com casca de eucalipto para avaliação das propriedades mecânicas do material. Para tal, foram utilizadas três formulações para a produção do compósito: a primeira formulação foi composta por polipropileno com a adição de 20 % de casca de eucalipto, 5 % de látex e 2 % de anidrido maléico; a segunda foi composta por PP com 20% de casca de eucalipto, 2% de PP-MAH e 0 % de látex; a terceira formulação, composta por 100% de polipropileno. Os ensaios mecânicos realizados foram de resistência à tração, resistência à flexão e resistência ao impacto. O delineamento experimental utilizado foi o inteiramente casualizado (DIC) e os dados foram submetidos a análise de variância; as médias foram comparadas pelo ensaio de Tukey a 5% de probabilidade, utilizando-se o software Sisvar. Os resultados mostraram uma diminuição das propriedades de resistência a flexão e a tração nos compósitos que contém casca de eucalipto e um aumento nas propriedades de impacto quando comparadas ao PP puro.PALAVRAS-CHAVE: polímeros, resíduo florestal, agente compatibilizante. PRODUCTION AND MECHANICAL CHARACTERIZATION OF POLYPROPYLENE AND EUCALYPTUS BARK COMPOUNDABSTRACT: In consequence of environmental concerns, the development of new technologies and high-performance materials has been directed towards to the field of sustainability, through the use of natural and renewable resources. Natural fibres are increasingly used as reinforcement in thermoplastics because of their low cost, high specific properties and renewable source. The addition of natural fibres to polymeric compounds can cause changes in their properties, characteristics and mechanical behavior, therefore the need for studies that deal with the production and characterization of these materials. Polypropylene (PP) modified with maleic anhydride (PP-MAH) is the compatibilizer most commonly used to improve interfacial adhesion between wood (hydrophilic) fibers and polypropylene (hydrophobic). Thus, and due to the versatility and industrial applicability of the plastic compounds reinforced with natural fibres, the objective of the present work was the production of a polymer matrix composed of eucalyptus bark and PP to evaluate the mechanical properties of the composite. Therefore, three formulations were used to produce the composite: the first formulation was composed of polypropylene with the addition of 20% eucalyptus bark, 5% of latex and 2% of PP-MAH; for the second composition, it was used polypropylene with 20% of eucalyptus bark, 2% of maleic anhydride and 0% of latex; the third formulation wascomposed of 100% polypropylene. The mechanical tests were of tensile and flexural strength and impact resistance. The experimental design was completely randomized and the data were submitted to analysis of variance; the means were compared by Tukey´s test at 5% probability, using the Sisvar software. According to the results, there is a decrease in flexural and tensile strength properties in composites containing eucalyptus bark and an increase in impact properties when compared to pure PP.KEYWORDS: polymers, forest residues, compatibilizing agent

ABSTRACT In this study, composites with three types of thermoplastic matrix and cellulosic material in a proportion of 40% were produced. The three thermoplastic matrices were high density polyethylene (HDPE), polypropylene (PP) and low density polyethylene (LDPE), and the cellulosic materials were pure wood flour (Pinus taeda L) or a mixture of wood flour and coconut shell flour (Cocus nucifera L) in equal ratios. The objective was to evaluate the influence of addition of coconut shell on the physico-mechanical properties (density, strength and rigidity) and the distribution of the cellulosic material in the thermoplastic matrix of the manufactured composites. It was found that the composites had a satisfactory distribution of wood flour in thermoplastic matrices, but the addition of coconut shell promoted bubble formation in the resulting pieces and, thus, interfered with the material properties. The use of a coupling agent promoted interfacial adhesion (cellulose - thermoplastic matrix), which was better in high density polyethylene composites, followed by polypropylene and low density polyethylene. In general, the coconut shell addition caused a decrease of all properties compared to composites made with Loblolly Pine. In addition, the interactions between thermoplastic type and cellulosic matrix type have been statistically confirmed, which caused variations in the studied properties

The management of thermosetting plastic solid waste has become serious issue worldwide due to its highly stable long-chain molecular structure and its recycling is the only way to reduce harmful effects. Also, depletion of natural resources like wood at alarming rate creates worldwide environment issues. In this article, feedstock filament for three-dimensional printing (in nonstructural engineering applications) of thermoplastic composite based on secondary (2°) recycled acrylonitrile butadiene styrene (ABS) as matrix reinforced with waste bakelite powder (BP) (thermosetting) and wood dust (WD) with twin-screw extrusion (TSE) process has been prepared (to impart desired mechanical/thermal/rheological and morphological properties).The results indicated that reinforcement of BP/WD initially increases the melt flow rate (MFR) of composite filament as compared to 2° recycled ABS. However, with increase in percentage of reinforcement beyond a certain limit, the MFR of the composite filaments starts decreasing. The mechanical, rheological, morphological, and thermal properties related to fused filaments prepared by TSE process have been explored in this research work and it has been observed that ABS composite filaments reinforced with 10% by weight of BP possess high peak strength (PS), high energy carrying capacity, more thermal stability, and contains low porosity. Based upon combined optimized extrusion parameter settings for maximizing the PS and percentage break elongation, 10 kg load, 225°C processing temperature, and 70 r min−1 are the best settings for both the composite filaments (ABS + BP, ABS + WD), and the corresponding values for ABS + BP and ABS + WD composite filament are 30.58 MPa (5.15%) and 25.65 MPa (6.05%), respectively.

Abstract Wood plastic composites have been prepared based on simul wood (Bombax ceiba L.), which was vacuum impregnated with the styrene acrylonitrile (SAN) co-polymer nanoclay (nnc) intercalating system in the presence of glycidyl methacrylate (GMA), a crosslinking agent. The impact of nanoclay was investigated on the mechanical, thermal, dynamic mechanical behavior, and the biodegradability of the resultant wood polymer nanocomposite (WPCnnc) was investigated. The tensile strength, tensile modulus, flexural strength, and flexural modulus of the composite were relatively higher in the presence of 2 phr nanoclay. The limiting oxygen index values showed self-extinguishing behavior of the WPCnnc. Furthermore, the storage moduli (E′) and damping index (tan δ) of these products were high. WPCSAN/GMA/nnc exhibit higher biodegradability compared to WPCSAN/GMA.

Full textAbstract:
The onsite wood frame method of constructing new buildings has been the norm for residential and basic commercial structures for more than a century. In this review study, we consider investment into plastic composite structures to supplement or replace wood frame home construction. Previous developments in this field often centralize on using a classic composite sandwich panel design: a polymer-based core material adjoined to layers of synthetic fiber-reinforced polymer (e.g. fiberglass). The core of the composite panels is designed to meet demands toward low cost, light weight, and structural rigidity. Different varieties of plastics, including thermosets and thermoplastics, are discussed. Factors that need to be considered in the fabrication of composite modular residential buildings include, but are not limited to, energy consumption (both in building heating and cooling, and fabrication energy usage), fire resistance, resource use, environmental impact, human impact, and cost. Basic fabrication principles and techniques for composite modular panels are reviewed, wherein mechanical and electrical work can be incorporated into the building during panel manufacturing. Methods in which panels can be fabricated in high volumes that enable economies of scale are described. Thusly, recent progress in the application of plastics forming and machining that is applicable to the construction industry, and the feasibility of this type of residential construction are elucidated and discussed holistically.

В настоящее время экструзия является наиболее распространенным технологическим процессом изготовления изделий из древесно-полимерных композиционных материалов с термопластичной полимерной матрицей. Эта технология может быть реализована методом послойного наплавления (FDM) для изготовления накладных декоративных элементов мебели, а также сувениров, игрушек и иной продукции. В качестве расходного материала применяется нить из разных типов пластика. Исследованию подлежали образцы, напечатанные на FDM-принтере из древесно-полимерной нити на основе полилактида и древесной муки марки 120 по ГОСТ 16361-87 из хвойных пород древесины в соотношении 70/30. Все образцы были изготовлены на FDM-принтере (Creality 3D CR-10 5S) с размером сопла 0,2 мм. При использовании такого композитного материала цветовая гамма, структура поверхности изделий будет ближе к древесине. В процессе исследований были изучены физические свойства образцов, напечатанных при разных температурных режимах (190, 200, 210, 220 С). Результаты исследований показали, что температура печати на 3D- принтере оказывает влияние на ряд физических свойств формируемого материала, в первую очередь, на его плотность и цвет. Изменение плотности и цвета может быть вызвано деструкцией древесного вещества при высокой температуре, увеличением плотности упаковки макромолекул и влиянием других факторов. Не было обнаружено существенных различий в шероховатости поверхности и в содержании влаги у исследуемых образцов из древесно-клеевой композиции на основе полилактида и древесной муки. Currently, extrusion is the most common technological process of manufacturing products from wood-polymer composite materials with a thermoplastic polymer matrix. This technology can be implemented by the method of layer-by-layer fusion (FDM) for the manufacture of overhead decorative elements of furniture, as well as souvenirs, toys and other products. A filaments of various types of plastic is used as a consumable material. Samples printed on an FDM printer made from wood-polymer filament based on polylactide and wood flour of grade 120 according to GOST 16361-87 from softwood in a 70/30 ratio were to be investigated. All samples were manufactured on an FDM printer (Creality 3D CR-10 5S) with a nozzle size of 0.2 mm. When using such a composite material colors, the structure of the surface of products will be closer to the wood. In the course of research, the physical properties of samples printed at different temperature conditions (190, 200, 210, 220 С) were studied. The research results showed that the temperature of printing on a 3D printer affects a number of physical properties of the formed material, first of all, its density and color. The change in density and color can be caused by the destruction of the wood substance at high temperature, an increase in the packing density of macromolecules, and the influence of other factors. No significant differences were found in the surface roughness and moisture content of the samples from the wood-adhesive composition based on polylactide and wood flour.
