Abstract

This paper investigated the performance of coconut fibre particles as a filler material and highdensity polyethylene as matrix in polymer matrix composites (PMC). Three different particle sizes of the filler material were used in formulating the composite samples and the concentration of the filler material varied up to 40% by volume. The composite samples were prepared by injection moulding and kept at room temperature for 48 hours prior to testing in order to promote relaxation of stresses. The test specimens were prepared and tested in accordance with ASTM standards D638, D790, D256, and D785 for tensile strength, elastic modulus, flexural strength, impact strength and Rockwell hardness respectively. At optimum condition of volume fractions and particle sizes of coconut fibre-filler, the coconut fibre reinforced HDPE (CFRP) has 28.6 MPa, 800 MPa, 22.3 MPa, 55.0 J/m and 54.0 HR as optimum value for tensile strength, elastic modulus, flexural strength, impact strength and hardness. It can be concluded from the results obtained that the Coconut fibre reinforced HDPE showed improved performance for applications of HDPE.
