| 摘 要： | A series of glass fibre reinforced composites based on novel blend matrices were fabricated us-ing reaction injection moulding (RIM) processing.The blends were made of sub-sequentialinterpenetrating polymer networks of acrylic-polyurea or acrylic-copoly(urea-isocyanurate).Themechanical and thermal properties were characterized by tensile test and dynamic mechanical ana-lysis.The fracture data from single edge notch bend tests were analysed using fracture mechanicsfor the composites to give K_(IC) and G_(IC).The correlation between reaction kinetics and morphologyof the blend and the composite properties were discussed.The investigations showed that the novelblends have good bonding property on glass fibre,thus good processability in RIM,and the re-suited composites have good mechanical and thermal properties.
