Abstract

Now-a-days natural fibers such as sisal, flax, hemp, jute, bamboo, banana, coir etc. are widely used for environmental concern. In this work, a new material was developed which possess high strength to weight ratio. Two natural fibers such as sisal and hemp reinforced with epoxy matrix. These fibers were treated with NAOH (alkali treatment) for better fiber matrix adhesion, the hybrid composites were prepared by compression molding technique at room temperature with applied pressure 410.4 kg/cm2 for 3 hours pressurization time. The mechanical properties were characterized according to standards. The amount of reinforcement varied was 10%, 20%, 30% and 40%. Prepared specimens were examined for mechanical properties such as tensile strength and flexural strength. Hybrid composite with 30% wt of sisal & hemp fiber were found to posses higher strength (tensile strength = 25.11Mpa; and flexural strength = 96.14Mpa) among the fabricated hybrid composite specimens.
