Abstract:

Now day’s natural fibers as reinforcement have received more attention from the research community all over the world in preparing polymer composites. These natural fibers have lot of advantages over synthetic fibers. In this paper two natural fibers wild date palm and coir reinforced composites were fabricated using hand lay-up method which was a new effort and was not done elsewhere. Specimens were cut from the fabricated composite plates according to the ASTM standards. Universal Testing Machine was used for testing tensile and flexural strength of the composites. The impact strength of the composites was analyzed using Impact tester. Fiber length of 3mm, 6mm, 9mm, 12mm & 15mm was subjected to analysis. A higher tensile strength of 26.27Mpa and flexural strength of 67.35MPa was obtained for the fiber of length 12mm compared to the fiber length of 3, 6, 9 and 15mm. The Higher impact strength of 6.41 KJ/m2 was obtained for fiber of length 15mm. From this experimental study, it was observed that the fiber length greatly influences the tensile properties of reinforced composites.
