摘要：

The post-impact compression strength of a poly(aryl sulfone) (PAS) thermoplastic, Radel 8320, and a toughened epoxy, Fibredux 924, matrix carbon fibre composites is examined at room temperature, 80-degrees-C and 150-degrees-C after non-penetrating impacts at combinations of these temperatures. Various fracture modes were identified but not found to have any correlation with variations in measured residual strength. In general terms, increasing the temperature of compression testing has a significant effect on the post-impact compression strength, whereas the temperature of the impact event has a marginal effect. There is evidence that the growth of impact generated delamination is restricted at the high temperatures during compression compared to growth at room temperature in the case of the epoxy matrix (thermoset), but this is not the case for the thermoplastic PAS.
