The ballistic impact experiments are conducted to investigate the damage of double-spaced aluminum plates impacted by the pressed and sintered PTFE/Al/W reactive material projectile. The experimental results show that a typical KE perforated hole on the front plate is produced by the reactive material projectile impact, whereas the dramatically structural damage with significant deflections and cracks is found in the rear plate, with larger ruptured holes and damage areas, as compared with the front plate. Moreover, the influences of the impact velocity and the plate thickness on the damage of the rear plate are analyzed by using the crack growth theory. The structural damage mechanisms of the rear plate are discussed.
