为研究加入不同官能化碳纳米管对环氧树脂力学性能的影响,通过对羧基化多壁碳纳米管(MWCNTs-COOH)进行化学处理,得到表面接枝乙二胺的碳纳米管(MWCNTs-EDA).分别将MWCNTs-COOH和MWC-NTs-EDA分散在环氧树脂中,通过热熔法制备环氧树脂中含有碳纳米管的T700碳纤维预浸料,并热压成准各向同性复合材料层合板.结果表明:MWCNTs-EDA在环氧树脂中的分散性优于MWCNTs-COOH,MWCNTs-EDA本身具有固化反应活性,加入后对基体的交联密度影响较小.与MWCNTs-COOH相比,MWCNTs-EDA可以有效改善环氧树脂及碳纤维/环氧树脂复合材料的力学性能.当MWCNTs-EDA含量为1.0wt％时,MWC-NTs-碳纤维/环氧树脂准各向同性复合材料层合板的压缩性能、弯曲性能和冲击后压缩强度分别提高了14.7％、40.9％和20.6％.
