is present project investigated the impact penetration response of woven jute fiber reinforced composites subjected to wide range of low impact velocities. Hand layout woven jute fibers are thermally compressed to ensure no internal defects formed in the composites. Six layers of woven jutes are stacked together using different fiber orientations [0/q/0]s. Low impact velocities are used ranging between 5 – 20 m/s. Force-time, force-displacement and energy-time curves are obtained automatically during the impact tests. The results are then discussed with considering the composite fragmentations and failure mechanisms. It is found that 00composite orientations capable to absorb sufficiently impact energy for 5 m/s but not for velocity greater than 10 m/s. When fiber orientations used between 15 – 450, the composite impact resistance increased indicating two significant peak forces. These peak forces represent different type of failure mechanisms occurred during the striker progresses.

AbstractPseudoelastic fiber-reinforced metal matrix composite with enhanced ductility and energy absorption capacity was developed. This composite system relies on the distributed nature of large pseudoelastic strains to mitigate localization of inelastic deformation and failure, and thus mobilizes a major fraction of volume for effective energy absorption. The pseudoelastic fibers were made of Ni-Ti-Cr alloy used in conjunction with two different matrices, aluminum and copper. Tension and pull-out tests were performed to evaluate the ductility and energy absorption capacity of control and pseudoelastic fiber-reinforced composites. Experimental results confirmed the ability of pseudoelastic fibers to induce distributed inelastic deformation within metal matrix composites for realizing major gains in ductility and energy absorption capacity.
