Abstract

Fiber is a natural or synthetic substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The combinations of the two types medium giving a specific function where the fiber act as the reinforcement in the composite to provide the strength for overall of the composite. Recently, the production of composite resource are focusing on a combination of elements used must be towards to technology-friendly environment, where it can affect low rate pollution for the long term durations. In this study, kenaf fibers is choosed and mixed with epoxy resin to form fiber reinforced polymer composites which improves the strength of the composites. Then, the kenaf fiber is sorted in uni-directional and bi-directional position. The mechanical properties of fiber or polymer composite are analyzed and compared between uni-directional and bi-directional orientation in order replace synthetic fibers. The result shows that the modulus of elasticity increased with increment of fiber composition but after 40 wt.% of kenaf fiber the modulus of elasticity was drop but the energy absorption remain increase until 70 wt.% and decrease after 70 wt.%. The effect of different orientation of kenaf fiber and epoxy was observed and potentially to replace synthetic fiber in order to reduce usage of synthetic fiber. Overall of this study output shows that the good bonded between fiber, proper strength distributions, and correct percentage of fibers are tend to obtain the good mechanical properties of the fiber composites.
