Impact properties of natural fiber-reinforced epoxy foams

This paper deals with the impact behavior of natural fiber-reinforced epoxy foams. The effects of different, types of fibers, fiber content and void content were discussed. It; was found that the woven flax fiber results in composites with better impact strengths than the woven jute fiber based composites. The impact damage configuration and mechanism of these laminated composites were discussed. Impact properties such as loss energy and damping index were found to be almost linearly dependent on void content and impact energy. The loss energy and damping index were decreased with increasing fiber content under comparable void content and test conditions.
