Abstract
Natural fiber reinforced composites are becoming used more frequently in building materials, automobile parts, and athletic products in addition to aeronautical structures. Because of their high strength and modulus, natural fibers are receiving more attention when it comes to development and use. The present study is based on the fabrication of composites of thermoplastic polyurethane (TPU) with 10%, 20% and 30% by weight of sisal fiber (Natural fiber) using injection molding technique and testing of samples to measure the tensile and flexural strength of composites. To enhance the mechanical properties, Sisal fiber is then passed through the chemical treatment (with 8%wt NaOH and 10%wt acetone+MA) process. Chemically treated sisal fiber is then mixed with TPU as per the composition (10%, 20%, and 30% by weight) to make three samples of each composition for tensile and flexural testing. Sample fabrication has been done as per ASTM standards. The test results indicate that the tensile and flexural strength of composites is better than pure TPU. The mode of failure of samples was examined through SEM
