Abstract

A novel experimental configuration that can simultaneously record projectile velocity histories and target back surface out-of-plane motion in penetration experiment is presented. The technique was used to investigate failure mechanism during ballistic impact of an S-2 glass fiber woven composite with 60 percent fiber volume fraction. Microscopy studies performed on recovered samples clearly show interply delamination, fiber breakage, ply inelasticity, and fiber kinking as the major failure modes in the composites. Recorded penetrator velocity histories indicate the failure process is rate dependent.
