Abstract

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