Abstract: In this paper, the effect of filler content is studied on water absorption behavior and impact strength for jute epoxy composite. Plain woven jute fabric is used as reinforcement. The resin system consists of Epoxy resin and Hardener in the ratio 10:1 by weight. Alumina (average particle size of 40 µm) is used as filler. The effect of filler content on water absorption behavior and impact properties studied by varying the filler content from 5%, 10%, 15% with respect to weight of epoxy resin. The composite laminates were fabricated using hand lay-up technique and cured under 30 bar pressure for about 24 hours. ASTM standards were followed to conduct these tests. It was clearly observed that unfilled specimen has the highest saturated moisture content and 15% filled specimen has lowest value. As filler content increases resistance to moisture absorption also increases. The water diffusion coefficient of composite was calculated using the diffusion coefficient equation. As filler content increases diffusion co-efficient decreases for alumina filled juteepoxy composite. Impact strength was found to be increase with the increase in the filler content up to 10 wt%.
