Composite materials are being extensively studied for ballistic armor. Their main advantage is connected to the possibility of deeply reducing weight and costs by maintaining high performances in terms of strength and security. Epoxy composites are reinforced with natural fibers which are replacing other synthetic reinforcement materials. Composites are prepared using polymers as matrix material because of ease of production with different reinforcements. The mechanical strength of the natural fiber reinforced polymer composites has been compared with synthetic fiber reinforced polymer composites and it is found that for achieving equivalent mechanical strength of the material, the volume fraction of the natural fiber should be much higher than synthetic fiber. This work being an experimental study on untreated “as received” fique fabric-reinforced epoxy composites, to demonstrate the potential of this renewable source of natural fiber for use in a number of applications.

Recently, natural fiber reinforced polymer composites have become popular over traditional synthetic fiber reinforced polymer composites for automotive, low demanding structural and semi-structural applications. In this work, a comparative study of a natural fiber composite such as jute fabric composite (JFRP) and synthetic fiber composite such as glass fiber composite (GFRP) is presented. The composites were manufactured using hand lay-up and then curing at 90°C for 10 min in a hot press, followed by 24 h room temperature post-curing. The mechanical properties such as tensile and bending of JFRP and GFRP composites, were evaluated and compared. It was revealed that even if GFRPs exhibited significantly higher mechanical properties than JFRPs, environmental impact would still favor JFRPs for non-structural and low load bearing applications.

This paper deals with tensile properties of natural fiber reinforced polymer composites. Natural fibers have recently found increasing use in various fields as an alternative to synthetic fiber reinforced polymers. Due to this they have become attractive to engineers, researchers and scientists. Natural fibers are replacing conventional fibers such as glass, aramid and carbon due to their eco-friendly nature, lesser cost, good mechanical properties, better specific strength, bio-degradability and non-abrasive characteristics. The adhesion between the fibers and the matrix highly influence the tensile properties of both thermoset and thermoplastic natural fiber reinforced polymer composites. In order to enhance the tensile properties by improving the strength of fiber and matrix bond many chemical modifications are normally employed. In most cases the tensile strengths of natural fiber reinforced polymer composites are found to increase with higher fiber content, up to a maximum level and then drop, whereas the Young’s modulus continuously increases with increasing fiber loading. It has been experimentally found that tensile strength and Young’s modulus of reinforced composites increased with increase in fiber content [1].

In recent years, significant academic and industrial research and development has explored novel methods of creating green and environmentally friendly materials for commercial applications. Natural fibers offer the potential to develop lower cost products with better performance, sustainability, and renewability characteristics than traditional materials, particularly in the automotive industry. In this respect, natural fiber reinforced polymer composites have emerged as an environmentally friendly and cost-effective option to synthetic fiber reinforced composites. Hence, in this study, a review of the tribological behavior of natural fiber reinforced polymer composites has been undertaken to better understand their usability for various automotive applications.

Glass fiber reinforced polymer composites were prepared by dispersing zinc oxide (ZnO) whiskers in resin matrix. Static and dynamic tensile tests of the as-prepared composites were performed by means of a universal testing machine and the split hopkinson tensile bar (SHTB), respectively. Good tensile properties, which can be affected by the strain rates, of the composites are obtained. The fracture section morphology of the composites was investigated by scanning electron microscope (SEM). The different failure of the composites under static and dynamic tension is found. The tensile properties of the composites are dominated by pull-out and fracture of fiber bundles. The influence of ZnO whiskers on the performance of composites has been discussed. ZnO whiskers, which have unique three-dimensional structures and corresponding stress transfer, contribute to the tensile properties of the composites.
