Abstract:

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.

Abstract:

Mechanical properties of wood plastic composite, prepared from acrylate-styrene-acrylonitrile (ASA) and bagasse, were investigated. In this study, 10 to 50 phr of bagasse were used in order to obtain the wood plastic composite with superior mechanical properties. The wood plastic composites in the study were prepared by melt-blending technique. All materials were mixed by using a two-roll-mill, shaped into sheets by a compression molding machine and the specimens were cut with a cutting machine. Youngs modulus, flexural strength, flexural modulus, impact strength and hardness of the wood plastic composites were investigated and found to improve with increasing bagasse content. However, some composite properties, i.e., impact strength, was decreased by adding the bagasse and then become steady when the amount of bagasse added was more than 30 phr. It was concluded that wood plastic composites with the desirable mechanical properties can be formulated using ASA as the matrix polymer and 50 phr of bagasse.

Abstract:

This paper aimed to confirm which adhesive is more suitable to glue the PVC wood-plastic composite materials between epoxy adhesive and J-39 acrylic ester adhesive. This paper tested compression shear strength and aging properties of PVC wood-plastic composite materials glued with these two adhesives. The results show that compression shear strength of PVC wood-plastic composite materials glued with epoxy adhesive is higher than with J-39 acrylic adhesives. Meanwhile, the setting time of two adhesives has effect on compression shearing strength. The results of aging properties after boiled and UV light treatment show that bonding properties of PVC wood-plastic composite materials glued with two adhesive were both degraded after aging，but bonding properties glued with epoxy adhesive was better than acrylic ester adhesive.

Abstract:

Three types of composite materials, Al-10Ni-6Ce (at%)/pure Al (Vf=0.3), Al-10Ni- 6Ce/Al-3.6Mn (Vf=0.3) and Al-10Ni-6Ce/Al-5.5Mg (Vf=0.3), and monolithic Al-10Ni-6Ce alloy were successfully fabricated to a fully dense rod-shaped bulk form having a diameter of about 10mm by adopting a powder forging or extrusion process using amorphous Al-Ni-Ce powder together with crystalline pure Al, Al-Mn and Al-Mg powders. The monolithic Al-Ni-Ce specimen forged at 648K showed a very high compressive strength of 1.3GPa without exhibiting any compressive plastic strain. All of the composite specimens forged at 648K gained a compressive plastic strain with the considerable sacrifice of strength. In contrast, Al-Ni-Ce/Al-Mg composite specimen extruded at 648K showed a noticeably high compressive strength of 1.2GPa with the compressive plastic strain of 0.5%. The extruded Al-Ni-Ce/Al-Mn composite specimen also exhibited a considerably high compressive strength (1.1GPa) accompanied with plastic strain (0.2%).

Abstract:

To solve the high-temperature rutting problem of asphalt pavement, the old rubber of the tire rubber and plastic of general polyethylene waste composite modified asphalt mixture is proposed. The plastic and rubber compound particle was made by the rubber through efficient desulfurization additives, pre-swelling, twin-screw extrusion equipment. The particles mixed with the asphalt mixtures specimen preparation and the dynamic stability experiments, composite beam fatigue experiments, flexural tensile strength and modulus experiments and anti-reflective pavement cracks and other mechanical experiments are performed. The comparative data obtained by the rubber and plastic composited modified asphalt mixtures and SBS asphalt mixtures prove that the rubber and plastic composited modified asphalt mixtures have excellent rutting resistance and fatigue resistance.

Abstract:

Graphene nanoplatelets are two-dimensional carbon structure materials with single or multilayers graphite plane which possesses attractive characteristics. In this study, the environmental aging effect on interlaminar properties of graphene nanoplatelet containing different proportions (0.25, 0.50, 0.75 wt%) reinforced epoxy/carbon fiber (carbon fiber reinforced plastic) composite laminates including interlaminar shear strength and fracture toughness were investigated. The interlaminar properties of graphene nanoplatelets/carbon fiber reinforced plastic composite laminates were improved over that of neat carbon fiber reinforced plastic composite laminates. Experimental results showed that the composite laminates containing graphene nanoplatelets possesses the appreciable improvement. The mechanisms responsible for the interlaminar enhancement were identified by studying the fracture surfaces using field emission scanning electron microscopy.

Abstract:

3D printing has rapidly become popular in both industry and private use. Especially fused deposition modeling has increased its popularity due to its relatively low cost. The purpose of this study is to increase knowledge in the mechanical properties of parts made of wood-plastic composite materials by using 3D printing. The tensile properties and impact strength of two 3D-printed commercial wood-plastic composite materials are studied and compared to those made of pure polylactic acid. Relative to weight –mechanical properties and the effect of the amount of fill on the properties are also determined. The results indicate that parts made of wood-plastic composites have notably lower tensile strength and impact strength that those made of pure polylactic acid. The mechanical properties can be considered sufficient for low-stress applications, such as visualization of prototypes and models or decorative items.

Abstract:

The improvement in impact properties of wood plastic composite from acrylate-styrene-acrylonitrile (ASA) and bagasse was reported in this work. The effect of type and content of impact modifier by using styrene-butadiene-rubber (SBR) and ethylene-acrylic acid (EAA) as impact modifier on morphology and mechanical properties of wood plastic composite were investigated. Wood plastic composites, prepared from ASA and 50 phr of bagasse by varying amount of impact modifier (both SBR and EAA) from 0-40 wt% of ASA were prepared by melt-blending technique. All materials were mixed by using a two-roll-mill, shaped into sheets by a compression molding machine and specimens were cut with a cutting machine. Then, the obtained materials were characterized, including morphology, impact strength and flexural properties. From SEM micrographs showed that wood plastic composites with using SBR as impact modifier showed more compatible with ASA matrix than EAA. This is a consistency results with mechanical properties such as impact properties, which indicated that the impact strength was improved with increasing the amount of SBR from 0-40 wt% of ASA. However, wood plastic composite with EAA showed the reduction of impact strength. So, it could be demonstrated from this study that the most appropriate impact modifier for wood plastic composite from ASA and bagasse was styrene-butadiene-rubber.

Abstract:

The abundance of waste plastic is a major issue for the sustainability of the environment as plastic pollutes rivers, land, and oceans. However, the versatile behavior of plastic (it is lightweight, flexible, strong, moisture-resistant, and cheap) can make it a replacement for or alternative to many existing composite materials like concrete. Over the past few decades, many researchers have used waste plastic as a replacement for aggregates in concrete. This paper presents a comprehensive review of the engineering properties of waste recycled plastic. It is divided into three sections, along with an introduction and conclusion. The influence of recycled waste plastics on the fresh properties of concrete is discussed first, followed by its influence on the mechanical and durability properties of concrete. Current experimental results have shown that the mechanical and durability properties of concrete are altered due to the inclusion of plastic. However, such concrete still fulfills the requirements of many engineering applications. This review also advocates further study of possible pre-treatment of waste plastic properties for the modification of its surface, shape, and size in order to improve the quality of the composite product and make its use more widespread.

Abstract:

Mechanical properties of the calcium-plastic composite have a great influence on the containers. The main factors affecting the mechanical properties are the process and material formulations. This paper mainly describes its impact of the addition of coupling agent. Under the usage of analysis of variance on single factor experiment, the mechanical properties of the calcium carbonate-plastic composite with three different coupling agents (silane, titanate and aluminate) were studied in the same test conditions. The results show that: The type and quantity of the coupling agent effect a lot on the mechanical properties of the composite. The silane coupling agent is the most suitable for calcium carbonate-plastic composite packaging materials, and the compatibility of calcium carbonate and polyethylene can be improved. When the silane coupling agent was at a 2.25 wt. % concentration, the tensile and flexural strength were improved obviously, especially the tensile strength increased by 23.24%, but the impact strength improved slightly.

Abstract:

The material replacement of component is often used procedure, which helps to reduce production costs, simplify manufacturing, improve functional properties of component and bring another benefits. In the last years, more and more metal parts are converted to plastic, also in the cases of mechanically loaded parts. For these special applications, the fibre reinforced composite plastics are successfully used. However, the mechanical properties of composite plastic are strongly dependent on the fibres orientation and following anisotropic behaviour. Moreover, the orientation of fibres is influenced by the conditions of the part production. Due to the number of these dependencies, the material conversion becomes a complex task which cannot be solved with analytical approach. Especially in case of complicated part geometry. In this study, the connection of two different numerical solvers was used for material conversion of a part from automotive industry. First, the new geometry of analyzed part was designed in order to compensate lower mechanical properties of plastic in comparison to metal. Next, the new part manufacturing was simulated and this way obtained anisotropic properties of composite plastic were described. Finally, the structural analyses of original metal and new composite plastic part with real anisotropic properties were performed to verify achievement of material conversion. The aim of this study is to demonstrate, how numerical analyses can help to predict an unexpected result.

Glass wool is discontinuous glass fiber with the average diameters of 3-4 μm produced by means of centrifugal process, and mainly applied to heat and acoustic insulation. But, there are few reports on glass wool applied to reinforcement of plastic materials in which chopped strand made by chopping continuous glass fiber is used primarily. In this study, the polyamide 66-based composite material samples containing glass wool were prepared and its wear property as a mechanical property was evaluated. It was found that the composite has an advantage on the wear property compared with a conventional glass fiber reinforced plastic, and the result suggests that glass wool has a possibility as a reinforcement material applied to plastic parts required wear resistance.

Abstract:

This study investigated the dimensional stability and strength properties of plastic bonded composites produced from wood waste particles and polyethylene using extruder. The composites were produced from wood species such as such as: Triplochiton scleroxylon, Terminalia superba and Gmelina arborea at a mixing proportion of 60:40 (plastic/wood) on a weight by weight basis. Evaluation of properties was carried out in accordance with the American Standard Testing Methods of 570 and 790 to determine the dimensional stability and strength properties of the composites. The results of findings revealed that water absorption and thickness swelling of the wood composites ranged from 10.08% to 15.36% and 4.33% to 5.58% respectively after 24hours and 48hours immersion in water. Tensile strength also ranged between 29.4MPa and 45.6MPa. Composite board made from T. superba wood particles had the lowest significant water absorption (10.08%), thickness swelling (4.33%) and highest significant tensile strength (45.6MPa) compared to composites produced from G. arborea and T. scleroxylon wood particles. It was observed that high density wood species exhibit lower water intake, lower thickness swelling and higher tensile strength, while the contrary is the case for lower density wood species. In conclusion, the three tree species used for the study could be recommended for the production of wood composite like particle board, fibre board, wood cement boards and others.

Abstract:

Composite materials with plastic matrix consist of a fiber material, which is used as the core and a matrix material, which forms the volumetric majority around that fiber material. Glass fiber reinforced plastics (GRP) are polymer-based plastic matrix composites that are used in a wide range of applications. In this work, a plastic-based composite material, which is used in tractor bonnets, was produced and thermal analysis and scanning electron microscopy (SEM) analysis of fracture surfaces for this material were performed. The SEM images of the fractured surfaces of the composites showed varied extents of fiber pull-outs under tensile failure modes. The nature of interfacial adhesion was discussed on the basis of the SEM study. A good correlation was established between the SEM study and the mechanical strength properties of the composites. However, it was observed that vinyl ester resin is a more suitable matrix for tractor bonnet parts due to its higher thermal resistance compared with orthophthalic resin.

Abstract:

Exact relationships are derived between instantaneous overall thermal stress or strain vectors and instantaneous overall mechanical stiffness or compliance, for two binary composite systems in which one of the phases may deform plastically. Also, the local instantaneous thermal strain and stress concentration factors are related in an exact way to the corresponding mechanical concentration factors. The results depend on instantaneous thermoelastic constants and volume fractions of the phases. They are found for fibrous composites with two distinct elastically isotropic or transversely isotropic phases, and for any binary composite with elastically isotropic phases. The results indicate that in the plastic range the thermal and mechanical loading effects are coupled even if the phase properties do not depend on changes in temperature. The derivation is based on a novel decomposition procedure which shows that spatially uniform elastic strain fields can be created in certain heterogeneous media by superposition of uniform phase eigenstrains with local strains, caused by piecewise uniform stress fields which are in equilibrium with prescribed surface tractions. The method is extended to discretized microstructures, and also to the analysis of moisture absorption and phase transformation effects on overall response and on local fields in the two composite materials.

Abstract:

Physical proprieties of particleboard, medium-density fiberboard, and wood-plastic composite board were studied by measuring the thickness and weight changes during repeated humidity cycling (RHC). The thickness stability, moisture absorbing capacity, and internal band strength of the control and treated specimens were measured for the three tested materials. The wood-plastic composite board showed the greatest stability, with only small changes in thickness and weight. Temperature is a key component of RHC treatment, with greater thickness changes after six cycles at 50 °C than after nine cycles at 20 °C. Compared with the control materials, the thickness stability of RHC-treated materials was decreased by 23.7 to 31.8%; RHC decreased the internal bond strength of specimens 22 to 23% for particleboard and medium-density fiberboard and 2.15% for wood-plastic composite board. Overall, thickness stability and internal bonding strength of the tested materials were highly correlated.

Abstract:

In this study, wastes of wood cutting mills (wood flour) as well as wastes of textile industry (granules of polypropylene) were used in manufacturing wood-plastic composites. Hence, wood flour with weight percent of 30, 35 and 40 was mixed with corresponding amount of polypropylene and coupling agent, polypropylene grafted maleic anhydride in amount of 6 percent was used in whole compounds. Production was done by batch method and with employment of hot press and after preparation and cutting of specimens physical and mechanical properties of them was studied. The results showed that with increase of wood flour up to 35 percent, MOR, MOE, water absorption and thickness swelling increases but further than it mechanical and physical properties decreases. Besides, increase of wood flour up to 40 percent increased the hardness of the specimens.

Abstract:

Outdoor applications of wood-plastic composites (WPCs) have raised question about the durability of such materials. WPCs are vulnerable to weathering factors such as UV radiation, moisture and freeze-thaw action. Weathering can cause discoloration, chalking, dimensional changes and loss of mechanical properties.This comparative study examines the effects of increased moisture content and artificial weathering on the properties of wood-plastic composites. Five commercial wood-plastic composite products from five different manufacturers were chosen and their water absorption, thickness swelling, impact strength and resistance to artificial weathering analyzed. An in-house manufactured wood-polypropylene composite with carbon black pigment was used as a reference product. In addition to quantitative investigation of material properties, the measured values were also compared with the values reported by the manufacturers.The composite samples were exposed to accelerated weathering in a xenon weathering chamber for 500 hours. The color change was estimated by spectrophotometer method. The weathering resulted in no significant color fading of the composites. After weathering, the general trend was a minor decrease in impact strength. Also the water absorption and thickness swelling of commercial WPC products remained on a low level.

Abstract:

Wastes such as saw dust (Pinus Radiata) and milk bottles (High Density Polyethylene - HDPE) are available in abundance. Composite decking materials, consisting of different weight percentages (60%, 70% and 80%) of saw dust and recovered HDPE, were extruded using a co-rotating, conical, twin screw extruder with a decking-profile die. The extruded decking materials were evaluated on their surface finish and shape conformance. The extruded decking materials were tested in accordance with the appropriate ASTM standards to determine their water absorption, thickness swell, static coefficient of friction, weathering and flexural (four-point bending) properties after they met the required quality ratings.

Abstract:

In the present article, a highly heat-resistant composite with a high fiber volume fraction ( Vf > 60%) was successfully manufactured using engineering plastic Nylon66 as matrix and carbon fabric as reinforcement by a solution impregnation molding method. The mechanical properties of the composite were investigated using a tensile measuring device. Mechanical analysis revealed the superior mechanical properties of the composite relative to those of previously reported carbon fiber-reinforced thermoplastics (CFRTPs). The cross section and fracture surface of the composite were characterized by scanning electron microscopy. The resin successfully impregnated the fiber bundles and the bonding strength of the fiber–resin interface was excellent. Dynamic mechanical analysis was used to evaluate the heat-resistant property of the composite. The composite exhibited a better heat-resistant property relative to that of the carbon fiber-reinforced crystalline co-polyester composite. To further verify the versatility of this method, super engineering plastic polyetherimide with a higher molecular weight was successfully employed as matrix to prepare CFRTP.

Abstract:

Wood plastic composite (WPC) materials represent modern materials that are attracting interest worldwide. WPC are composite materials and they have properties of both components – plastic and wood. WPC materials are formed by combining two substances – discontinuous reinforcements (wood particles or cellulose microfibers) and a continuous binder (plastic matrix), in a certain proportion. The authors describe WPC machined surfaces after turning. On the basis of a set of experimental data collected by surface and mechanical tests obtained from the WPC materials, the mechanical deformation work was evaluated, the value of which presents specific information about the material as a specific material coefficient.

Abstract:

Wood-plastic composites for 3D printing from plant fiber (bleached pulp powder, mechanical pulp powder, newspaper pulp powder, eucalyptus powder, pine powder, and lignin) and polylactic acid (PLA), with silane coupling agent (KH550) as plasticizer, were prepared via melt extrusion. The physical properties, such as surface morphology, apparent density, tensile strength, melt flow rate, compatibility, and thermal stability were measured. Moreover, the effects of the content of various types of plant fiber powder in PLA on the properties of the prepared composites were investigated. The results showed that the modified lignin/PLA composite exhibited a superior performance under the same added amount. In particular, when the amount of lignin added was 15%, the tensile strength of the composite was 74.0% higher than that of pure PLA, and the melt flow rate was reduced by 17.8% compared with pure PLA. The density of the composite increased 15.8% compared with pure PLA when the lignin content was 20%. The scanning electron microscopy cross-sectional morphology and differential scanning calorimetry analyses showed that the optimal addition amount of lignin was 15%. Finally, the prepared lignin/PLA composite material was used in 3D printing with a smooth silky property and an excellent printing performance.

Abstract:

Based on the finite element analysis software ABAQUS, the CT specimens of bimetallic material and the metallurgical composite bimetallic pressure tube with axial crack were simulated on the fracture mechanical properties, after that the crack growth residual strength and the plastic failure stress of the metallurgical composite bimetallic pressure tube model were obtained. The results indicate that the crack growth residual strength generates near the crack tip and the crack growth residual strength of the pressure tube model is smaller than the CT specimens. Meanwhile, the plastic failure stress values obtained from the CT specimens and the pressure tube model are basically consistent with the theoretical calculative values. With the crack depth a increasing, the plastic failure stress values will be reduced. For the same crack depth, the plastic failure stress values of the pressure tube model are slightly lower than the CT specimens and the theoretical calculative values.
