Abstract

An integrated experimental and computational study of residual compressive strength of composite laminate sandwich structures after low velocity impact (CAI strength) is performed using samples consisting of 8 ply graphite/epoxy face sheets bonded to aluminum honeycomb core. The study encompasses characterizing the indentation damage (dent depth and laminate fractures), measuring the CAI strength for a range of layups and core densities and computational modelling of indentation and CAI strength.
