Abstract

The susceptibility of laminated graphite/epoxy composite plates to delamination and spalling was determined experimentally for different types of loading conditions. Sixteen ply, 32 ply, and 48 ply composite plates were subjected to low velocity impact loads and equivalent quasi-static loads. Preliminary impact tests were performed to establish the lower bound or incipient damage and the upper bound or spalling damage. Different energy levels were selected to generate the progressive damage data for plates of varying thickness subjected to low impact velocity loads. The static and impact tested laminates were C-scanned to identify the internal damages.
