Abstract

This report describes the effects of recycling on the mechanical properties of composites based on oil palm fiber in a polypropylene (PP) matrix. Composites, containing 30wt% fiber with 3wt% maleated polypropylene (MAPP) as a coupling agent, were recycling up to six times. For this composite, tensile strength (TS) and Young modulus (YM) were found to decrease with increased numbers of recycling by up to 9.6% for TS and 4.7% for YM (after recycled six times). Flexural test were also carried out for this composites and flexural strength were found to decrease by 23.8% with increase number of times recycled. The recycled processed had influenced the hardness of the palm fiber composites. The hardness numbers of the composites were found to increase with increased number of times the materials were recycled. The fiber composites showed an average hardness number of 72.10 which increased by 7.43% after being recycled six times to 77.89.
