Hyper velocity impact studies simulating debris collision on composites material

This paper describes the hyper velocity impact test to composite material. The composite material is already adopted as a structural material of many space craft. On the other hand, there is little debris collision data to composites material. Then, the hyper velocity collision experiment to the board of composite material was conducted by making board thickness, diameter and velocity of projectile into parameter. While the fracture situation by collision, internal damage, and residual compression strength are measured, since we acquired new knowledge, we report the relation between collision energy and damaged area.
