Abstract

Malaysia is one the largest producers and exporters of palm oil in the world, accounting for 11% of the world's oils & fats production and 27% of export trade of oils and fats. However, the milling process is highly inefficient, with only 10% of the mass can be extracted to become palm oil. Most of the byproduct are usually discarded or burned. Thus, this study aims on using on one of the wastes of the process, empty fruit bunch (EFB), to be the reinforcement phase material for a polymer matrix composite. As a result, 4 types of oil pam empty fruit bunch (OPEFB) fiber polymer matrix composite with different fiber to epoxy ratio has successful been fabricated. It is analysed that the increase in fiber content in the composite will reduce the tensile strength of the material. As a composite, the material must undergo secondary process after the process is done to eliminate flashes/burrs that occurs during the machining process, and to ensure the correct dimensions. Thus, the cutting force of the composite samples of different fiber ratio are measured by using dynamometer. The cutting force data were analyzed and it is shown that the weight percentage of material plays a huge part in the cutting force of the composite. The higher the OPEFB fiber content, the lower the cutting force is.
