The aim of the present study is to investigate the dynamic mechanical and thermal properties of hybrid jute/sisal fibre reinforced epoxy composites. The hybrid composites were prepared by hand layup technique having total fibre loading of 30% by weight with different weight ratios of jute and sisal fibres. Dynamic mechanical properties such as storage modulus ([Formula: see text]), loss modulus ([Formula: see text]) and damping ([Formula: see text]) were investigated in the temperature range of 30–200 ℃. The thermal stability of the prepared composites was studied using thermogravimetric analysis. Other thermal properties such as glass transition temperature ( Tg), crystallization temperature ( Tc) and decomposition temperature ( Td) were also obtained by differential scanning calorimetry. The results indicated a positive effect of hybridization in terms of increase in dynamic mechanical and thermal properties. Storage modulus, loss modulus and Tg were found to be higher for hybrid composite having a higher percentage of jute fibres.

In recent trend, the most used fiber reinforced composite is the glass fiber composite. The glass-fiber composites have high strength and mechanical properties but it is costlier than sisal and jute fiber. Though the availability of the sisal and jute fiber is more, it cannot be used for high strength applications. A high strength-low cost fiber may serve the purpose. This project focuses on the experimental testing of hybrid composite materials. The hybrid composite materials are manufactured using three different fibers - sisal, glass and jute with epoxy resin with weight ratio of fiber to resin as 30:70. Four combinations of composite materials viz., sisal-epoxy, jute-epoxy, sisal-glass-epoxy and sisal-jute-epoxy are manufactured to the ASTM (American Society for Testing and Materials) standards. The specimens are tested for their mechanical properties such as tensile and impact strength in Universal Testing machine. The results are compared with that of the individual properties of the glass fiber, sisal fiber, jute fiber composite and improvements in the strength-weight ratio and mechanical properties are studied.

The fibers from naturally available resources are considered to have potential alternate reinforcing agent in polymer matrix composite materials due to their properties such as high strength, stiffness, degradable in nature and renewable in nature. In this study a lightweight, low cost and environment friendly hybrid composites are prepared by using sisal-jute-glass fibers as the reinforcement materials. There are three types of composites such as sisal/glass fiber reinforced polymer (SGFRP) composites, jute/glass fiber reinforced polymer (JGFRP) composites and sisal/jute/glass fiber reinforced polymer (SJGFRP) composites are prepared by hand lay-up process and underwent to charpy impact test in order to study their impact properties. Post impact induced damage, material failure mechanism, matrix cracking, fiber breakage and pullout was observed by using scanning electron microscopy (SEM) analysis. The results showed that the energy absorption and load carrying capacity of JGFRP composites are better and able to withstand higher loads than SGFRP composites and SJGFRP composites. It is further observed from the experiment, the inclusion of sisal and jute fibers with glass fiber reinforced polymer (GFRP) composites has gained good impact properties. It is suggested that these light weight sisal and jute fibers have been used as an alternative reinforcing material to synthetic fiber for medium load applications.

Because of biodegradability, low weight, non-da000nger, instability, decreased condition, contamination, little effort, and simplicity of recyclability, natural fibre polymer composites are now being utilized in place of synthetic fibre reinforced polymer composites. By altering the fibre and epoxy percentages, to find the effect of sisal fibre content on mechanical characteristics of composites is the objective of research. Melt-mixing was used to make the composite, which was then laid out by hand layup method. The purpose of this research is to look at fibre oriented reinforced composite polymer nano composite materials that mix with hybrid composites such as JUTE, SISAL/EGG SHELL, and epoxy polymer in the ratio of sisal fibre 70% + jute 20% + Egg shell 10% and sisal fibre 60% + jute 20% + Egg shell 20% by volume. The mechanical characteristics were calculated by performing tests on the specimen’s tension, hardness, and flexural qualities in line with ASTM standards.

Abstract Natural fibers (NF) have gained prominence over synthetic reinforced fibers due to their advantages, such as a high strength-to-weight ratio and renewability, compared to synthetic fiber reinforced composite fibers. Fibers such as sisal, palm, banana, and jute are commonly utilized in NF reinforced matrix composites because of their favorable mechanical properties, low density, biodegradability, and high strength-to-weight ratio. The dynamic mechanical properties of the composite are influenced by the interaction between these different components. The intention of this exploration is to investigate the influence of Dynamic Mechanical Analysis (DMA) on alkaline-treated sisal, palm, banana, and jute fibers. The mixtures curves of the storage modulus (Energy storing) (E′), loss modulus (dissipation of energy) (E”), and damping factor (absorbs and disperses energy) (Tan ) were obtained utilizing DMA. The variance of E′ showed an improvement from 1.47 for the AT1(20% palm and 20% jute) to 1.66 for the composites containing 20% banana and 20% jute fiber, indicating an improvement in viscoelastic stiffness of the matrix. The increased jute/banana fiber inclusion, the greater the effective stress, and thus the superior E”. Tan decreased significantly as the fiber reinforced portion increased, indicating improved interfacial relations linking fiber and resin. These findings support the application of sisal fiber/epoxy as a good potential polymer reinforced composites for automobile components.

In recent years, natural fiber reinforced composites (NFRCs) have gained significant attention due to their potential to replace synthetic fibers in various applications. This research focuses on developing green composite materials by combining sisal, jute, and bamboo natural fibers with epoxy resin filled with Coconut Shell Powder (CSP) and Ground Granulated Blast Furnace Slag (GGBS). The composites were fabricated using hand layup and bag molding processes with varying fiber volume fractions of 5%, 10%, and 15%. The results showed that GGBS-filled composites exhibited superior tensile strength, flexural strength, and impact strength, with average tensile strength enhancements of 18.3% (Sisal), 19.9% (Jute), 15.3% (Bamboo), and 10.7% (Hybrid fibers). Additionally, GGBS-filled composites displayed higher Shore D hardness, with Bamboo-GGBS exhibiting a 14.45% higher hardness than Bamboo-CSP. Furthermore, water and oil absorption percentages were reduced by 24.5% (water) and 32.1% (oil) for Sisal, 22.1% (water) and 29.5% (oil) for Jute, 26.3% (water) and 34.1% (oil) for Bamboo, and 23.2% (water) and 30.5% (oil) for Hybrid. EDAX and SEM analyses confirmed the composition and microstructure of the developed NFRCs, revealing strong interfacial bonding, uniform filler distribution, and distinct energy levels of constituents. Overall, these NFRCs, made from Sisal, Jute, and bamboo fibers filled with CSP and GGBS, offer a durable and sustainable solution for various industries, including automotive, aerospace, medical devices, renewable energy, and construction.

A thermal gravimetric analyzer analyzed the thermal adsorption properties of developed composites with the temperature range of 28°C–650°C at a 20°C/min constant heat flow rate. The epoxy hybrid composites were synthesized using natural jute/sisal fibre hybridized with the addition of synthetic E-glass fibres at 0-degree, 0/90-degree, and intralaminar orientations through the wet filament-winding process. The effects of orientations on tensile, flexural, and impact strengths of epoxy hybrid composites were studied using ASTM D3039, D790, and D6110. The evaluated results were compared, and the epoxy hybrid composite containing intralaminar orientations found better thermal stability with reduced weight loss at 650°C. Similarly, the test result for mechanical studies of the hybrid composite showed superior tensile, flexural, and impact strengths. The epoxy hybrid composite with intralaminar orientation was found to have a maximum tensile, impact, and flexural strength of 61.91 MPa, 770.61 J/m, and 83.90 MPa, respectively.

The application of lignocellulosic fibers as reinforcements in composite materials has found increasing use in recent years, due to the attractive characteristics of natural fibers such as their low cost, high specific modulus, biodegradability, abundance and with many technical qualities. Natural fiber hybrid composites are very frequently used in automotive aerospace and other industries. In this work, numerical and experimental analysis is carried out to compare curauá, jute and sisal fibers in epoxy composites for use in industry. The most appropriate hybridization effect by establishing the amounts of each fiber on the mechanical properties was considered. Finite Element Models were designed and validated through mechanical tests. The number of Finite Element models and specimens performed was determined through the design of experiments using the Taguchi Method and then the results were statistically validated. Higher strength was obtained in composites made with curauá fiber, followed by jute and sisal fibers. Such behavior was achieved by FEM and experimental tests, revealing an increase in tensile strength by increasing the amount of fibers up to 35% in total. Higher strength was achieved when the composite was made with curauá (20 wt.%), jute (10 wt.%) and sisal (5 wt.%) fibers. The results show a good agreement between the FEM and the experimental tests. Furthermore, the results of the present study were compared with those obtained previously mentioned in the open literature.

AbstractOffshore wind turbines are utilized for wind power harvesting through wind farms installed in bodies of water, normally at sea. The blades of the wind turbine resist the airflow and rotate and generate useful mechanical energy. Most of these wind blades are made of synthetic glass and carbon fibers. Synthetic fiber has higher mechanical strength but is non‐biodegradable in nature. The hybrid synthetic and natural composite materials overcome the non‐biodegradable issues to a certain extent and exhibit higher mechanical strength. In this prelude, the present work utilizes sisal, jute and rubber with epoxy‐based hybrid material used for wind blade manufacturing. The hybrid composite materials used in the present work have the volume fraction of synthetic fibers, natural fibers, and resin as 40 %, and 30 %, respectively. CATIA modelling software package is utilized to design the three‐dimensional model of the wind blade and is imported into the ANSYS Workbench. The structural, harmonic, and modal analyses are carried out, and the performance of the wind blades made of different hybrid composite materials is compared. Further, the computational fluid dynamic study is carried out to visualize the proposed composite offshore wind turbine's flow distribution. The results revealed that the proposed hybrid glass/jute/epoxy composite material yields better results and is more suited for offshore wind blade manufacturing.

Objective: This study aims to analyze the fractography of polymeric composites reinforced by recyclable materials, verifying the main types of defects present in the manufactured materials. Theoretical Framework: Composites can be understood as mutltiphasic materials that present a significant portion of the properties of their constintuintes. There are two phases, matrz and reinforcement. From the fractofrgographic analysis of the fracture surface of the material, one can evaluate the mechanisms of failure and interaction between the interfaces of the phases. Method: Specimens were manufactured using silicone molds according to ASTM D638. The matrix was unsaturated and pre-accelerated terephthalic polyester resin, while the reinforcement materials were: Jatoba wood residues, the hybridization of Jute and Sisal fibers, the hybrid of sisal and coffee grounds, and açaí leaves. Results and Discussion: For the composite with reinforcement of wood waste, there was a predominance of voids. For hybrids, the presence of the fibers culminated in the pull-out defect, therefore, using sisal fibers and coffee grounds, the presence of voids was also observed. The composite with acai leaves presented delamination between the reinforcement layers and the matrix. Research Implications: The analysis of the predominant defects, evaluates the possibility of improvement of the manufacturing process in order to certify the presence of this and promote and improve the efficiency of handling the material. Originality/Value: The use of natural and recyclable materials is of great importance from a sustainable analysis. In addition, it aims to generate added value to raw materials with little or no functionality.

Research on natural-fiber-reinforced polymer composite is continuously developing. Natural fibers from flora have received considerable attention from researchers because their use in biobased composites is safe and sustainable for the environment. Natural fibers that mixed with Carbon Fiber and or Glass Fiber are low-cost, lightweight, and biodegradable and have lower environmental influences than metal-based materials. This study highlights and comprehensively reviews the natural fibers utilized as reinforcements in polyester composites, including jute, bamboo, sisal, kenaf, flax, and banana. The properties of composite materials consisting of natural and synthetic fibers, such as tensile strength, flexural strength, fatigue, and hardness, are investigated in this study. This paper aims to summarize, classify, and collect studies related to the latest composite hybrid science consisting of natural and synthetic fibers and their applications. Furthermore, this paper includes but is not limited to preparation, mechanism, characterization, and evaluation of hybrid composite laminates in different methods and modes. In general, natural fiber composites produce a larger volume of composite, but their strength is weaker than GFRP/CFRP even with the same number of layers. The use of synthetic fibers combined with natural fibers can provide better strength of hybrid composite.

The conventional method of fiber reinforced polymer (FRP) wrapping around concrete columns uses epoxy as the binder along with synthetic or natural fibers such as carbon, glass, basalt, jute, sisal etc. as the reinforcement. However, the thermal stability of epoxy is a major issue in application areas prone to fire exposure. The current work addressed this major drawback of epoxy by modifying it with a nanofiller, such as multiwalled carbon nanotubes (MWCNT), and reinforcing it using basalt and sisal fibers. The effect of exposure to elevated temperature on the behavior of concrete cylinders externally confined with these FRP systems was analyzed. Three types of specimens were considered: unconfined; confined with sisal fiber reinforced polymer (SFRP); and confined with hybrid sisal basalt fiber reinforced polymer (HSBFRP) specimens. The test samples were exposed to elevated temperature regimes of 100 °C, 200 °C, 300 °C and 400 °C for a period of 2 h. The compressive strengths of unconfined specimens were compared with various confined specimens, and from the test results, it was evident that the mechanical and thermal durability of the FRP systems was substantially enhanced by MWCNT incorporation. The reduction in the compressive strength of the FRP-confined specimens varied depending on the type of the confinement. After two hours of exposure at 400 °C, the compressive strength corresponding to the epoxy–HSBFRP-confined specimens were improved by 15%, whereas a 50% increase in strength corresponding to MWCNT-incorporated epoxy–HSBFRP-confined specimens was observed with respect to unconfined unexposed specimens. The MWCNT-modified epoxy-incorporated FRP-confined systems demonstrated superior performance even at elevated temperatures in comparison to unconfined specimens at ambient temperatures.

Natural fiber polymer composites have been largely used in applications like aerospace, automotive, marine, and other civil structures, where mechanical and tribological properties are of prime consideration. The performance of hybrid composites can be improved by using different natural fibers and adding particulate fillers to them. In this study, mechanical and tribological properties of jute/sisal/E-glass fabrics reinforcing matrix such as natural rubber and epoxy filled with different proportion of tungsten carbide (WC) powder were studied. Mechanical properties like tensile strength, flexural strength, impact strength, and also tribological behavior like two-body abrasive wear of composite were studied. Taguchi technique was employed for wear analysis. Results revealed that there is a significant change in the mechanical properties and enhancement of wear behavior was noticed due to the incorporation of filler (WC) particles.

Abstract Hybridization of natural and synthetic fibers has the ability to improve composite performance. It means that the combination of natural fibers such as coir, jute, bamboo, and sisal with synthetic or glass fiber can broaden the role of the composite material, especially for structural application. This study developed a finite element simulation to investigate the damage to the bow structure of the fishing boat hull, which was produced using hybrid coir-glass fiber composite (HCGFRP) material subjected to front collision load. The experimental measurement was conducted to determine the mechanical properties of four hybrid composite laminates defined based on the differences in their layers number, fiber types, and orientation angle. Moreover, a numerical simulation model was applied to the traditional fishing boat colliding with fishery harbor quay, and the scenario was defined by varying the boat speed and the types of laminates adopted on the hull structure. The results showed the damage level for the bow structure of the HCGFRP boat due to the collision accidents, while the numerical findings are expected to be used as the basic knowledge in applying the hybrid coir-glass fiber laminates composite as an alternative hull construction material.

The application of adhesively bonded joints in automotive industry has increased significantly in recent years mainly because of the potential for lighter weight vehicles, fuel savings and reduced emissions. The use of composites in making automotive body components to achieve a reduced vehicle mass has also continuously increased. Natural fibre composites have recently attracted a great deal of attention by the automotive industry due to their many attractive benefits (e.g. high strength-to-weight ratio, sustainable characteristics and low cost). However, the literature on natural fibre-reinforced polymer composite adhesive joints is scarce and needs further investigation. The main objective of this study was to evaluate and compare the mechanical performance of adhesively bonded joints made of synthetic- and natural fibre-reinforced polymer composites. Similar and dissimilar single lap joints bonded with a modern tough structural adhesive used in the automotive industry, as well as the epoxy resin AR260 (the same resin used in composite fabrication) were tested. It was found that the average failure loads varied significantly with adhesive material strength and adherend stiffness. Furthermore, it was also observed that failure mode has a significant effect in failure load. The jute-based natural fibre composites joints, both hybrid and purely natural, were superior in strength compared to the sisal-based natural composites joints.

Multifunctional fibrous systems were developed within this research work, giving special importance to the electrical conductivity and antibacterial activity. The functionalization of several natural fibres (jute, sisal, coir, flax and cotton) with silver nanoparticles (Ag NPs) was successfully achieved using a sustainable and eco-friendly method, namely polyethylene glycol (PEG) reduction. FESEM images, GSDR and ATR-FTIR analysis show that the Ag NPs were incorporated onto the fibres surface. The resistivity values obtained by analysing the fabrics without functionalization was about 1.5x107 Ω.m while with the Ag NPs functionalization the resistivity values decreased almost 15000 times, to 1.0x 103 Ω.m. Jute fibres’ antibacterial efficiency was also studied using the fibres with incorporated nanoparticles. Jute/Ag NPs showed some activity against E. Coli and S. Aureus. Polylactic acid (PLA) was used to develop flexible biodegradable composites with the functionalized jute. The compatibilization of the jute with PLA was successful and the characterization of the final composites was performed by GSDR, ATR-FTIR and TGA.

Jute ( Hibiscus cannabinus L. & H. sabdariffa L.) and allied fibres (mesta, sunnhemp, ramie, sisal and flax) play an important role in Indian economy. Raw jute (jute and mesta) farming, industry and trade provide liveli- hood support to about 5 million people in India and is grown in an area of about 1.0 million ha. Despite a two- fold increase in the productivity of jute since independence, the area is stagnant for last two decades. The acre- age of other fibre crops like ramie and sisal has not increased substantially though ramie and sisal fibres are costlier than raw jute, sunnhemp and cotton. The increased cost of cultivation of jute and the fluctuating market price often affects the farmers. So to enhance the profitability of jute and allied fibre farming, we have to intro- duce high value crops as components of jute-based cropping systems besides extending their cultivation to non-traditional areas. Ramie has shown a good growth and yield at Nilgiri hills, Goa, Maharastra while sisal has a great potential in the dry areas like western Orissa, Madhya Pradesh, Jharkhand. Diversification and value addition to the end products is needed as there is wide scope in the global market and the part of the ad- ditional profit must reach the farmers to motivate them. Jute ( Corchorus capsularis L. & C. olitorius L.) is the main commercial crop of the eastern and north eastern India providing livelihood security to about 5.0 million people (4.0 m farmers, 0.25 m mill workers and 0.50 m people engaged in jute based ancillary sectors). It is grown in an area of little over 0.8 m ha, producing nearly 10 million bales (1 bale 180 kg.) of fibre, which is about 40% of the worlds' production. Mesta is grown in an area of 0.15 m ha with a production of 1.0 m bales. The major jute growing states are West Bengal, Bihar, Assam, Orissa, Uttar Pradesh, Meghalaya and Tripura while mesta is mostly cultivated in Andhra Pradesh, Maharastra, Orissa and Bihar. Sunnhemp ( Crotalar ia juncea L.) is cultivated mostly in Bihar, Uttar Pradesh, Madhya Pradesh, Rajasthan, Maharastra and Tamil Nadu.

Due to environmental concerns, natural fibre development is essential, and its utilization has recently attracted more attention. The use of jute, hemp, linen, sisal, and banana fibres in textile production is widespread around the world. Additionally, these fibres are widely accessible in many countries, including Pakistan, India, China, Turkey, and the United States. The objective of this study is to compare the physio-mechanical characteristics of the aforementioned natural fibres. All of these fibres were obtained locally. Scanning electron microscopy was used to examine the surface morphology of these natural fibres, and the results revealed that banana and sisal fibres are hollow in comparison to other fibres. A single fibre tensile testing apparatus was used to evaluate the mechanical characteristics. Banana and sisal fibres demonstrated the highest breaking strength and elongation, respectively. Fourier transform infrared spectroscopy was used to investigate the functional groups of these natural fibres. Differential scanning calorimetry and thermogravimetric analysis were used to investigate their thermal behaviour. Energy Dispersive X-Ray Analysis and Raman analysis were also carried out to ascertain the chemical composition.

Now-a-days traditional materials are replacing the natural fibres in automobile components like dashboards, seat-backs and interior trims due to its properties like light weight, environment friendly, good stiffness and high strength to weight ratio . In the study three different continuous fibres, Acacia, Jute and Sisal were mixed in varying proportion with GFRP and epoxy resin on a determined ratio basis to get three different composite samples. These fibres were alkaline treated and moulded using compression moulding and hand lay-up technique. These samples were tested for their Tensile and Impact strengths to find the specimen with higher strength. Scanning Electron Microscope (SEM) test was also conducted to study the structure of all three specimens after tensile test. The study concludes that the sample ‘A’ which has maximum content of sisal has higher tensile strength than other two samples. Similarly impact test concludes that specimen ‘B’ and ‘C’ which has maximum content of Jute and Acacia has equal and higher strength.

Numerous studies have been conducted recently on fibre reinforced concrete (FRC), a material that is frequently utilized in the building sector. The utilization of FRC has grown in relevance recently due to its enhanced mechanical qualities over normal concrete. Due to increased environmental degradation in recent years, natural fibres were developed and research is underway with the goal of implementing them in the construction industry. In this work, several natural and artificial fibres, including glass, carbon, steel, jute, coir, and sisal fibres are used to experimentally investigate the mechanical and durability properties of fibre-reinforced concrete. The fibres were added to the M40 concrete mix with a volumetric ratio of 0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5%. The compressive strength of the conventional concrete and fibre reinforced concrete with the addition of 1.5% steel, 1.5% carbon, 1.0% glass, 2.0% coir, 1.5% jute and 1.5% sisal fibres were 4.2 N/mm2, 45.7 N/mm2, 41.5 N/mm2, 45.7 N/mm2, 46.6 N/mm2, 45.7 N/mm2 and 45.9 N/mm2, respectively. Comparing steel fibre reinforced concrete to regular concrete results in a 13.69% improvement in compressive strength. Similarly, the compressive strengths were increased by 3.24%, 13.69%, 15.92%, 13.68% and 14.18% for carbon, glass, coir, jute, and sisal fibre reinforced concrete respectively when equated with plain concrete. With the optimum fraction of fibre reinforced concrete, mechanical and durability qualities were experimentally investigated. A variety of durability conditions, including the Rapid Chloride Permeability Test, water absorption, porosity, sorptivity, acid attack, alkali attack, and sulphate attack, were used to study the behaviour of fiber reinforced concrete. When compared to conventional concrete, natural fibre reinforced concrete was found to have higher water absorption and sorptivity. The rate of acid and chloride attacks on concrete reinforced with natural fibres was significantly high. The artificial fibre reinforced concrete was found to be more efficient than the natural fibre reinforced concrete. The load bearing capacity, anchorage and the ductility of the concrete improved with the addition of fibres. According to the experimental findings, artificial fibre reinforced concrete can be employed to increase the structure’s strength and longevity as well as to postpone the propagation of cracks. A microstructural analysis of concrete was conducted to ascertain its morphological characteristics.

The demerits of plain concrete are its lesser tensile strength, not significant ductility and poor resistance to cracking. Due to propagation of internal micro cracks in plain concrete causes decrease in tensile strength, hence leads concrete to brittle fracture. Addition of fibres behaves like crack arrester and enhances the dynamic properties of concrete. In India natural fibres such as bamboo, coir, jute, sisal, pineapple, banana, ramie etc are high available. Jute is a useful natural fibre for concrete reinforcement due to its easy availability and low cost. In this research, the experiments related to Jute fibre reinforced concrete (JFRC) are done by taking different fibre percentage and the compressive strength and modulus of rapture value observed. This JFRC can replace plain concrete and wood in many cases for example in door and window panels, inclined roof slabs, partition walls etc

It has been identified that the mechanical properties increase with the increase of volume fraction of fibres to a certain extent and then decreases. The hybridization of the reinforcement in the composite shows greater mechanical properties when compared to individual type of natural fibres reinforced. For all the composites tested, the tensile strength of the composite increased up to 25% of volume fraction of the fibres and further for the increase in the volume fraction of fibre the mechanical properties were decreased. As same as tensile properties, the flexural and impact strength also increased linearly up to 25% of volume fraction of fibres and further for the increase in the volume fraction of fibre the mechanical properties were slightly decreased.

ABSTRACT The inclusion of fibre reinforcement in concrete, mortar and cement paste can enhance many of the engineering properties of the basic materials, such as fracture toughness, flexural strength and resistance to fatigue, impact, thermal shock and spalling. In recent years, a great deal of interest has been created worldwide on the potential applications of natural fibre reinforced, cement based composites. Investigations have been carried out in many countries on various mechanical properties, physical performance and durability of cement based matrices reinforced with naturally occurring fibres including sisal, coconut, jute, bamboo and wood fibres. These fibres have always been considered promising as reinforcement of cement based matrices because of their availability, low cost and low consumption of energy. In this review, the general properties of the composites are described in relation to fibre content, length, strength and stiffness. A chronological development of sisal fibre reinforced, cement based matrices is reported and experimental data are provided to illustrate the performance of sisal fibre reinforced cement composites. A brief description on the use of these composite materials as building products has been included. The influence of sisal fibres on the development of plastic shrinkage in the pre-hardened state, on tensile, compressive and bending strength in the hardened state of mortar mixes is discussed. Creep and drying shrinkage of the composites and the durability of natural fibres in cement based matrices are of particular interest and are also highlighted. The results show that the composites reinforced with sisal fibres are reliable materials to be used in practice for the production of structural elements to be used in rural and civil construction. This material could be a substitute asbestos-cement composite, which is a serious hazard to human and animal health and is prohibited in industrialized countries. The production of sisal fibres as compared with synthetic fibres or even with mineral asbestos fibres needs much less energy in addition to the ecological, social and economical benefits.

This study investigates the creation of a pipeline flange using a hybrid polymer composite made from sisal and plantain fibre particles. Sisal/plantain hybrid composites are affordable, lightweight, and exhibit adequate mechanical properties, making them accessible and user-friendly. These natural fibres serve as effective alternatives to synthetic options and hold considerable potential to replace traditional steel materials. The sisal and plantain fibres were processed into particles sized between 300-500 μm. The hybrid composites were fabricated using the traditional hand layup technique, incorporating various percentage combinations of sisal and plantain fibres in laminates made from unsaturated polyester resin. The resulting laminate samples underwent a series of tests, including tensile, flexural, impact, compressive, and hardness tests, to evaluate their mechanical properties based on different fibre ratios. A ratio of 75% sisal to 25% plantain fibres yielded optimal performance, achieving a tensile strength of 10.2 MPa, a compression strength of 96.7 MPa, and a Rockwell hardness number of C19, indicating strong resistance to brittle fractures. The sisal/plantain fibre polyester composite flange produced at this ratio was further analyzed using Finite Element Analysis (FEA), providing insights into its structural behavior under varying pressure conditions. As pressure increased from 30 psi to 300 psi, the maximum von Mises stress in the flange rose steadily, peaking at 7.894 MPa at 300 psi. This result indicates a proportional response to mechanical loads, demonstrating that the hybrid materials significantly enhance the flange's structural integrity. Energy Dispersive Spectroscopy (EDS) analysis identified silicon (Si) as the predominant element in the sisal/plantain hybrid composite, whereas the cast iron sample was primarily composed of iron (Fe). Additionally, observations under Scanning Electron Microscopy (SEM) revealed a strong interfacial bond in the sisal/plantain fibre hybrid polyester composites, confirming their suitability for flange production. The standard sisal/plantain polymer hybrid flange was fabricated using the traditional hand layup method. It features a diameter of 150 mm, four bolts, 16 mm diameter holes, and a flange thickness of 25.4 mm, based on the 75%:25% fibre ratio.

Bond strength between embedded bar and concrete plays vital role in the design of various reinforced concrete structural elements. Use of metallic and synthetic fibres has been shown to be an effective method to enhance tensile strength, reduce shrinkage and improve durability properties of concrete. However, making of synthetic fibres will not only deplete the natural hydrocarbon resources, but also add greenhouse pollutants to the environment. Hence, sisal fibre was considered as a potential alternative to polypropylene fibre. An experimental study was conducted to evaluate the influence of sisal fibres as mono-fibre and in combination with steel as hybrid fibre on bond strength of concrete. The performance of steel polypropylene fibre reinforced concrete (SPFRC) is compared with that of steel sisal fibre reinforced concrete (SSiFRC). Bond strength was conducted onM30 grade concrete for curing periods of 7, 28 and 90 days. Fibre dosages of 0.50%, 1.00%, 1.25% and 1.50% by volume of concrete were used. Results indicated that increase in steel fibre dosage improved the bond strength slightly. However, increase in fibre dosage of either PP fibres or sisal fibres resulted decrease in bond strength. Furthermore, sisal fibre reinforced concrete (SiFRC) showed inferior performance in bond strength as compared to polypropylene fibre reinforced concrete (PFRC). A detailed statistical analysis revealed that although no strong correlation between the compressive strength and the bond strength was evident from the experimental study, means of bond strength of both the hybrid groups did not differ significantly. In addition, empirical equations were proposed to predict the bond strength of fibre reinforced concrete (FRC) based on compressive strength.

The hybrid composites were prepared using okra/sisal fibres of 30/70, 50/50, 70/30 fibre weight ratios, when subjected to varying weights of fibres (0. 4, 0. 8, 1. 2, 1. 6, 2) grams. The tensileand impact properties were carried out using hybrid composite specimens.

Full textAbstract:
Natural fiber is mostly used in automobile and aerospace industry. Currently most used in natural fiber reinforcement are sisal, flex, hemp, and banana. The natural fiber is mined by using manual and retting processes. The agricultural waste can be used to prepare fibers it has major advantage is renewable resources and have marketing demand. The polymer composite have many advantage such as mechanical strength such as tensile, impact and flexural strength over traditional glass fiber and monogenic materials. In this paper to fabricate the polymer composite with using on sisal and banana reinforcement with treated with NAOH solution. These processes are enhancing the bonding strength between fiber and resin by removing moisture contents. After fabricated polymer composite to prepare the samples as per ASTM standard, the samples are tested for different composition of sisal, banana and sisal banana reinforced composites. M.

Work presented is interested in the characterization of the quasistatic mechanical properties and in fatigue of a composite laminated in jute/epoxy. The natural fibres offer promising prospects thanks to their interesting specific properties, because of their low density, but also with their bio deterioration. Several scientific studies highlighted the good mechanical resistance of the vegetable fibre composites reinforced, even after several recycling. Because of the environmental standards which become increasingly severe, one attends the emergence of eco-materials at the base of natural fibres such as flax, bamboo, hemp, sisal, jute. The fatigue tests on elementary vegetable fibres show an increase of about 60% of the rigidity of elementary fibres of hemp subjected to cyclic loadings. In this study, the test-tubes manufactured by the method infusion have sequences of stacking of 0/90° and ± 45° for the shearing and tensile tests. The quasistatic tests reveal a variability of the mechanical properties of about 8%. The tensile fatigue tests were carried out for levels of constraints equivalent to half of the ultimate values of the composite. Once the fatigue tests carried out for well defined values of cycles, a series of static tests of traction type highlights the influence of the number of cycles on the quasi static mechanical behavior of the laminate jute/epoxy.

Hybrid composites prepared by using oil palm empty fruit bunch (EFB) and jute fibres as reinforcement in epoxy matrix by keeping the EFB/jute fibre weight ratio constant at 1:1. In this study, effect of coupling agent on tensile and flexural properties of oil palm empty EFB/jute fibres reinforced epoxy hybrid composites evaluated. Hybrid composites are prepared by using hand lay-up technique. Particular interest is the effect of coupling agent (CA), 2-Hyroxy ethyl acrylate (HEA) on the tensile and flexural properties of hybrid composites. The laminates coupled with HEA showed better tensile and flexural properties than the one without coupling agent. The highest tensile and flexural strength value has been obtained for hybrid composite of jute/EFB/jute (CA). Tensile fracture composite specimens were analyzed by using scanning electron microscopy (SEM) to know the morphological behaviour of composites. Thermal properties of the hybrid composites were investigate to observe the effect of 2-Hyroxy ethyl acrylate (HEA) on thermal stability of hybrid composites.

Now- a- days the polymers are frequently used in domestic and industrial purposes. The properties of polymer composites are somewhat inferior and may be improved with the addition of filler and fiber materials. Jute is one of most economical natural fibres and is obtained primarily from plant materials such as cellulose and Lignin. Sisal is a vegetable, natural, fully biodegradable fibre and which has good specific strength and stiffness and is used for making ropes and twines. The banana fibre is the strongest natural fibres and is made from the stem of the banana tree which. exhibits good tensile strength and incredibly durable and bio-degradable. An attempt is made to improve the properties of polymer composites using jute, sisal and banana fibers and addition of 2 % titanium di boride as filler material. The polymer composites were made by hand layup method with epoxy as matrix material. The mechanical properties of fabricated composites such as tensile and impact strength, hardness were evaluated as per ASTM standards. It is found that tensile strength, hardness and impact strength were improved with the addition of fibers and filler material. The micro structural evaluation is also carried out using scanning electron microscope and found that particles were dispersed in the matrix material.

Expensive and non-biodegradable synthetic fibres are commonly utilized as reinforcement in composites for better mechanical properties. The eco-friendly and low-cost properties of natural fibres are promising alternative reinforcement for composites. In this study epoxy-based glass and jute fibres reinforced hybrid composites are fabricated varying fibre stacking sequences, 1jute-1glass alternatively (j-g-j-) and 4glass-9jute-4glass (4g-9j-4g). Hybridization of jute and glass fibre results better tensile, flexural and water absorption properties than only jute fibre reinforced composites but inferior to only glass fibre reinforced composites. The 4g-9j-4g stacking sequence resulted in better mechanical and water absorption properties than j-g-j-- stacking sequence. The effect of chemical treatment and glass microfiber infusion are also investigated. Chemically treated jute fibre and 2 wt.% microfiber infused hybrid composite shows about 42% improvements in flexural strength as compared to untreated and without microfiber infused composites. However, fibre chemical treatment and microfiber do not have a positive impact on tensile strength.
