Effect Of Reinforced by Coconut Fiber Core on The Mechanical Properties for Un-Saturated Polyester Matrix Composite Material

Abstract

This work involves study tensile strength; hardness and thermal conductivity ofcomposite material consist of coconut fibers mixed with polyester resin. Thiscomposite material was prepared by adding three percentage of coconut shells (1,2 and3) wt% . addition of coconut shells improved mechanical properties for compositematerial with three percentages , while led to decrease thermal conductivity because itis behave as insulated material.
