Abstract

This research looks into the damage response and energy absorption behaviour of unidirectional carbon fibre-reinforced polymer (CFRP) composite panels subjected to low-velocity impact events. The response of CFRP composite materials with thermoset (TS) resin and thermoplastic (TP) PEEK polymer matrix are investigated. Evolution of impact force and absorbed energy with time during impact are presented for each TS and TP panel. Comparisons are provided between damage area obtained optically and using C-scanning technique. The investigations are based on the scanned images along with the characteristic force and absorbed energy curves for two material systems with TS and TP polymers, having similar stacking sequences, carbon volume fraction and thickness.
