【 摘 要 】

In this paper, fracture behavior and Mechanical properties of short banana fiber reinforced polymer composites is investigated. Fibers are extracted from banana plant,Further compositelaminates were prepared with randomly distributed fiberswith different weight fraction of banana ranging from 30%, 35% and 40%. Composites are prepared using hand layup technique. Tests were performed to determine fracture toughness (Mode I) and mechanical properties of these laminates. The tests were performed to examine the effect of weight fraction of fiber on the fracture toughness of the composite. As epoxy is a brittle material, stress intensity factor is utilized to evaluate the fracture toughness of the composites. From the experimental results were carried out on different weight fractions of banana. It is observed that the 40 % of banana fiber shows maximum fracture toughness, Composite plate of 30% shows the maximum tensile strength.
