Increasing the needs for different engineering applications invite the development of new materials. In the present research new natural fiber okra was introduced for the preparation of okra fiber reinforced polyester (FRP) composites. Already established fibers sisal and banana were also extracted for the preparation of sisal and banana FRP composites and to determine tensile properties. The tensile properties of okra FRP composites were compared with sisal and banana FRP composites. Hand lay-up technique was used for the preparation of composites. Chemically treated okra fiber reinforced polyester composites at maximum volume fraction showed tensile strength, modulus of 154.17%, 114.13% and specific tensile strength and modulus of 12.26%, 129.82% higher than that of the pure polyester specimen, respectively.Keywords

For Environmental concern on synthetic fibers (such as glass, carbon, ceramic fibers, etc.) natural fibers such as Sisal, flax, hemp, jute, kenaf etc. are widely used. In this research work, elephant grass fiber reinforced polypropylene matrix composites have been developed by injection molding technique with varying fiber percentages (0%, 5%, 10%, 15%, 20% and 25% by weight). The developed elephant grass fiber reinforced composites were then tested for their flexural and impact properties. The results show that flexural and impact properties increases with increase in the fiber percentage; however, after a certain fiber weight percentage, the properties are decreased. Elephant grass fiber introduced in the present study could be used as an effective reinforcement for making composites, which have an added advantage of being light weight.
