Abstract

Composite is one type of material in the world of engineering that is made by combining two types of materials that have different properties into one new material with different properties. Composites from fiber materials are continuously being researched and developed to become alternative materials to replace metal. There are many types of fibers that can be used as composite materials today, one of which is natural fiber. Indonesia is one of the countries that has many forests and mountains, which are overgrown with various wild plants or trees, from various types, many of which produce bamboo fiber and palm fiber. Rice husks as additional reinforcement in bamboo fiber and palm fiber composites and also to reduce waste that has not been widely processed and utilized. This study aims to determine the mechanical properties of bamboo fiber and palm fiber composites with additional rice husk particle fillers. To determine the mechanical properties of bamboo fiber and palm fiber composites with additional rice husk particle fillers, tensile and bending tests were carried out to determine the stiffness and strength values ​​of the composites. It begins with the composite manufacturing process, using polyester resin, fiber volume fraction and resin 40:60 with variations in fiber orientation direction 0° and 90°, and the manufacturing method used is hand lay up. From the results of the composite tensile test, it can be concluded that bamboo fibers in the longitudinal fiber direction (0°) have greater strength and stiffness than others. And from the bending test, it can be concluded that bamboo fibers in the longitudinal fiber direction (0°) still have a higher strength value, but in terms of elastic modulus, bamboo fibers have a higher value compared to palm fibers, so bamboo fibers have higher stiffness compared to palm fibers.
