摘要：

This paper presents results from mechanical tests on glass fibre-reinforced polypropylene laminates. Materials were manufactured in a press and the average rate of cooling from the forming temperature after pressing was varied from 0.23 to 55-degrees-C min-1. The cooling rate was found to affect the matrix structure and to strongly influence fracture behaviour. Faster cooling resulted in improved Mode I and Mode II fracture energies, and smaller delaminated areas after impact. Results are compared with those obtained on a glass fibre-reinforced thermoset polyester composite.
