摘要：

Poly(urethane-isocyanurate)(PUI) resin and glass fiber continuous strand mat reinforced PUI composites(CSM/PUI composites) were prepared by structural reaction injection molding process. Mode I interlaminar fracture behaviors by use of double cantilever beam (DCB) tests were studied. It showed G c varied significantly during crack propagation. G c of CSM/PUI composites were higher than that of the pure PUI resin because of the additional force required to fracture fiber bridging in CSM/PUI composites. Comparative DCB tests were carried out to demonstrate the occurrence of fiber bridging. G (I) (c) varied markedly and were much dispersed, which would induce little variation when initial crack length was 40 mm. The fracture characteristics were analyzed by scanning electron microscope.
