This review aims at explaining about the research and development in the improvement in properties of natural fibre reinforced polymer composites along with its application. The highest value of impact strength was obtained for 1 wt% nanoclay content bamboo–epoxy nanocomposites. The present study is to investigate the mechanical properties of sisal fiber reinforced composites. The fermented leaves were washed and sun dried. technologies is given together with the manufacturing methods, mechanical properties and applications associated with these materials. No synergistic effect was observed when APP was used in combination with Mg(OH)(2). Tensile strength increased about 45% for composites without providing holding time (0 minutes), while the bending strength value increased significantly to 103% obtained on composites given a holding time of 30 minutes. The physical and mechanical characterization showed that sisal fiber had better characteristics than sansevieria fiber. The chemically treated natural fibre shows, A composite material can be defined as a macroscopic combination of two or more distinct materials, having a recognizable interface between them. In the present investigation, analysis of the interfacial properties of self-reinforced polyamide composites by using microbond multiple fibre pull-out test is emphasised. The results showed that the composite with treated fiber at 20% fiber loading has shown 30% and 8% higher tensile strength than neat PLA and untreated sisal/PLA composite, respectively. The following natural fibers such as sisal, banana, kenaf, jute and oil palm are abundantly available and they are cheaper, possess superior mechanical properties. Demand for natural fibers reinforced composites is growing as an alternative to synthetic fiber reinforced plastic composites. The mechanical pr, bre-reinforced polymer composites have been studied by many, researchers and a few of them are discussed in this article. The GF/SF/CTS hybrid composite possesses a unique sandwich structure and comprises GF/CTS/epoxy as the external layers and SF/CTS/epoxy as the inner layers. The types of fibres, yarns and knit structures used to produce knitted fabric composites are presented along with the techniques used to combine them with different types of polymer matrices. The amount of fiber content in the composites varied with values of 10%, 20%, and 30% by volume. Finally, lower percentage by weight of sisal powder content promotes better mechanical properties and lower water absorption percentages; that is, the increase of the sisal powder content exhibits behavior inversely and directly proportional to the mechanical properties and to the percentage of absorption of water, respectively. FTIR and Fractographic studies are carried out for deep understanding of the post pull-out interfacial adhesion. Composites with woven sisal fibres showed higher values for tensile strength and ultimate strain, and lower modulus of elasticity than composites with randomly arranged sisal fibres.

Green plastics are constantly being used to minimize the negative impacts of the polymers made of fossil fuels such as petroleum. To Develop a Hybrid Composite Water Storage Tank, Interfacial adhesion of composite materials plays an important role in their mechanical properties and performance. In this work, sisal – fibres reinforced composites is developed and their mechanical properties such as tensile strength, compression strength and impact strength are evaluated. In casting temperature Laquan silica sol crust process suitable for the production of surface roughness is small, precision high accuracy in size, and has become the mainstream technology has been widely used. Most of the researchers concentrated only in the short form of natural fibres, this leads to dropping the fibre reinforcement in continuous and lengthy products. e best result was observed when MAPP treatment method was don, was also reported that increase in bre loadin, 30 and 17% higher than neat PLA, respectively, impact strength.

The flexural and impact strengths were maximum for the sisal fiber/polypropylene and maleic anhydride-grafted polypropylene composites, and its tensile strength was also improved significantly. Various fibre treatments, which are carried out in order to improve adhesion, leading to improved mechanical properties, are also discussed in this review paper. Test specimens were prepared with untreated fiber and treated with alkaline solution of sodium hydroxide. Besides, the matrix materials are often nonpolar and hydrophobic, and chemical bonding to the polar and hydrophilic natural fibers is difficult [1,4,5]. The SFs were mixed with a biodegradable material, polylactide (PLA), and the composites were prepared by hot press molding. The enhanced impact strength of bamboo–epoxy nanocomposites was one of the key advantages brought by nanofiller. For the sake of this review, strength, tensile modulus, exural strength, exural modulus a, strength of bre can be determined theoretically b, Flexural strength is the ability of a mat, Flexural strength is also known as bending strength, while exural modulus is also known, as bending modulus. The grafting had an impact on the thermal and mechanical properties of the composites, as determined by differential scanning calorimetry and tensile testing. Table 6. The tensile, hardness and impact tests were carried out of composites. Therefore, it is necessary to improve their interfacial adhesion to improve the comprehensive properties of composites. On the other hand, the use of natural fibres in composite materials, such as sisal fibres, in substitution for synthetic fibres, has increased considerably. 32 have studied the mechanical properties of sisal–glass fiber-reinforced low-density polyethylene matrix composites by taking into account the effects of fiber orientation. The mechanical and physical properties of sisal fiber not only depend on its source, position, and age which will affect the structure and properties but also depend on the experimental conditions, such as fiber diameter, gauge length, strain rate and test temperature. . Optical microscopy showed a decrease in spherulite formation, and hence controlled reduction of the crystalline region of the PHB matrix, with the addition of agave fibre and peroxide treated fibre.
