Abstract

The relevant alternative candidate to replace the synthetic and the different types of reinforcement was, the natural fiber by a reason it was a renewable resource. A raw material such as kenaf fiber been used to be replaced such as wood in pulp and paper industries to avoid the devastation of forests. Kenaf fiber was low cost, lightweight, easy production and friendly to the environment. Polyester (PE) was chosen because it was as well as good mechanical properties. Composites were materials made of a polymer resin reinforced by fibers, combining the high mechanical and physical performance of the fibers and the appearance, bonding together and enriching the physical properties of polymers. Therefore, the purpose of this research was to study and analyzed the new composition of kenaf fiber reinforced with PE resins towards the tensile test. Kenaf fiber and PE resin used in different percentage to get the best composite. The gel time process of the PE with MEKP hardener be done before fabrication process due to, to determine the curing time taken of resin at room temperature. From mixing the 5% until 70% kenaf fiber, PE, and MEKP hardener by using hand lay-up molding technique was known as fabrication process. The curing time for each sample will take 6 – 8 hours before the tensile test. After the curing process, the sample was tested for tensile testing and the modulus of elasticity for the samples was determined. The highest of a modulus of elasticity was 60% of kenaf fiber with 40% polyester resin. The increase of content fiber after 60% of kenaf fiber did not increase the modulus of elasticity. The morphology cross-section on the fracture area of the sample tensile test been observed by using SEM. The 60% fiber content of sample was the best in range for modulus of elasticity is 3.97GPa.
