摘　　要：利用真空辅助树脂灌注快速成型工艺(VARI)制备聚双环戊二烯(PDCPD)基碳纤维增强复合材料,研究两种材料的界面结合性以及复合材料的力学性能。结果表明:PDCPD基碳纤维增强复合材料的树脂质量分数达到40%时,该复合板材的拉伸强度接近400 MPa(高于同型号碳纤维复合环氧树脂板材),弯曲强度在300 MPa以上;通过扫描电镜(SEM)观察到PDCPD树脂黏附在碳纤维丝上,碳纤维与PDCPD树脂浸润结合性较好。Polydicyclopentadiene(PDCPD)based carbon fiber reinforced composites were prepared by vacuum assistant resin infusion process(VARI).The interfacial bonding of the two materials and the mechanical properties of the composites were studied.The results show that when the resin content of PDCPD based carbon fiber reinforced composite reaches 40%,the tensile strength of the composite plate is close to 400 MPa(higher than that of the same type of carbon fiber epoxy composite plate),and the bending strength is more than 300 MPa;the scanning electron microscope(SEM)shows that the PDCPD resin adheres to the carbon fiber filament,and the carbon fiber and PDCPD resin have good wettability.
