Influence of Coir Fiber Diameter and Length on Mechanical Behavior of Coconut Shell Powder–Based Polyester Resin Composites

Abstract Coir fiber is available in abundance in nature. Coconut shell is a food waste material. Both are procured from the coconut. Coir fiber–reinforced coconut shell powder–based polyester resin composite is fabricated by using the hand lay-up technique. Here, coir fiber acts as a reinforcing agent. Coconut shell powder acts as a filler material. Polyester resin acts as a binding material. Composites are fabricated as per ASTM standards. Tests of mechanical behaviors such as tensile strength and compressive strength are carried out, and the results are analyzed based on the influence of coir fiber diameter and length.
