Damage in CFRPs due to low velocity impact at low temperature

This work examines the response of carbon fibre-reinforced epoxy matrix (CFRP) laminates at low impact velocity and in low temperature conditions. Square specimens of carbon fibre/epoxy laminates with different stacking sequences (unidirectional, cross-ply, quasi-isotropic and woven laminates) were tested using a Drop Weight Tower device. The test temperature ranged from 20 down to −150 °C. After the impact tests, the damage extension was...
