Impact behaviour and damage tolerance of woven carbon fibre-reinforced thermoplastic composites
AbstractInstrumented drop weight impact and compression after impact test methods were used to assess the impact performance and damage tolerance of firm-stacked, woven carbon fibre-reinforced PEEK and woven carbon fibre-reinforced PPS composite systems. The tests were performed at three energy levels with a constant velocity, and at three velocity levels with a constant energy. Extreme energy of the levels were also determined. While the effect of the impact velocity was found to be significant within the range of the velocities used, the impact energy significantly affected the impact performance of the panels. Carbon fibre PPS panels evinced a high resistance to perforation by way of extensive delamination. On the other hand, carbon fibre PEEK panels showed an ability to confine the damage zone and hence, to markedly increase the damage tolerance of the panels. A set of material selection criteria for impact applications, based on the results of this study, has bee proposed
