Influence of Filler on Mechanical and Di-electric Properties of Coir and Luffa Cylindrica Fiber Reinforced Epoxy Hybrid Composites

Abstract

Natural fiber hybrid composites were prepared by Hand layup technique by reinforcing coir, silk squash, and CaCO3. Both coir and silk squash is maintained constant weight proportion of 10 wt. % and 5.7 wt. %, respectively, whereas as CaCO3 is varied with three different proportions (0, 2 and 4 wt. %). Mechanical and dielectric properties were evaluated on the fabricated composite samples. Influence of filler content on adhesive bonding of the fractured composite samples was studied using Scanning Electron Microscopy (SEM). Higher filler content in the composite attained high mechanical properties, similar with the dielectric properties as well. The potential applications of the present fabricated composite samples are found to be increase in automobile and building industry in near future.
