Tensile and Flexural Strength of OKRA Fiber Reinforced Polymer Composites

Increased environmental awareness and consciousness, has developed an increasing interest in natural fibers and its applications in various fields. Natural fiber reinforced composites plays a key role in engineering applications like automobile parts, car doors, furnitures etc. The present work aims to determine the tensile and flexural strength of the okra fiber reinforced composite in araldite LY556 resin. The fiber percentage is varied from 0 to 25% in steps of 5. The tensile test is conducted on specimens made according to ASTM D-638-1 and the flexural strength according to ASTM D-790. The tensile strength increased with the increase in % okra fiber upto 20% and thereafter it decreased. The flexural strength increased with increase in % okra fiber upto 10% and thereafter decreased.
