Description
Summary:This work is focused on development of hybrid composites with better toughness and hardness by including natural filler reinforcements. The changes in the behavior of the composite due to filler inclusion were evaluated through acoustic emission technique to reveal the mechanism behind the improvement in properties. The hybrid composite was developed with Hemp/Kevlar fibers in (60:40) ratio by weight as reinforcement. To improve the shock resistance, bio-fillers palm and coconut shell mixture in (1:1) ratio was added to the matrix at different wt.% of resin. Characterization of the material was carried out after the flexural, impact and hardness tests.
