Summary
Experimental studies of centrally impacted (0–90° lay-up) fiberglass-epoxy plates have revealed a sequential delamination mechanism, which appears to be a significant factor in the energy absorption at impact speeds below the speed required for perforation of the plate by a small rigid impactor. A linear relationship is found between impactor kinetic energy and total delamination area in this impact speed range (above a threshold speed) when the delamination does not extend to the edge of the plate.
