NATURAL FIBER REINFORCED POLYMER COMPOSITES

Abstract

Hybrid composites of epoxy matrix and four mixed fibers were prepared. The epoxy matrix is from BADGE and the hardener PPA-7040 mixed in 1:1 volume ratio. The four mixed fibers used for reinforcement are (i) murta bast + jute, (ii) murta bast + luffa, (iii) murta bast + coir, and (iv) murta bast + betel nut fiber. The hybrid composites were analyzed and characterized on the basis of density, water absorption, thermal gravimetric analysis, tensile/flexural/compressive/impact strengths and hardness studies. Murta and jute form the best mixture for making hybrid composite as this composite possess superior physical and mechanical properties. The amount of water absorbed by a hybrid composite does not appear to have any correlation with the chemical composition of the fibers used for reinforcement.
