摘　　要：采用反应性羧基丁腈橡胶(CTBN)对环氧树脂E-51(EP)进行了增韧改性,并制备了CTBN/EP复合材料,研究了不同用量CTBN增韧改性环氧树脂复合材料的性能。结果表明,采用15份CTBN对EP进行增韧改性,并以2-乙基-4-甲基咪唑作固化剂在100℃下制备的CTBN/EP复合材料综合性能满足要求。Epoxy resin E-51(EP)was toughened by reactive carboxyl nitrile butadiene rubber(CTBN),and CTBN/EP composites were prepared.The properties of epoxy resin composites modified and toughened with different content of CTBN were studied.The results showed that the comprehensive properties of CTBN/EP composites prepared by using 15 phr CTBN to toughen EP and using 2-ethyl-4-methylimidazole as the curing agent at 100℃met the requirements.
