摘要

To study the damage effect of different projectile structures and jacket materials of PELE upon perforation of multi-layered plates, an experiment of three different kinds of projectiles impacting on multi-layered plates was conducted. The experimental results show that the layered PELE can change the characteristics of fragments broken by jacket which include quantity, mass and the area of distribution. The jacket of layered structure PELE can generate more number of fragments of uniform quality and centralized distribution than common PELE. So it results in the occurrence of cumulative damage effects on target plate. Using the W fiber /Zr-based amorphous matrix composites as the jacket material of PELE, the jacket can be broken into lots of single W fibers and W fiber bundle fragments, and the fragments distribute centrally. The impulse of the fragments loads on the plate intensively, which reduces the plate resistance and improves the opening size substantially.
