摘要
在603环氧树脂中加入0.25%(质量分数,下同)、0.50%和1.00%的羧基化碳纳米管(MWCNTs-COOH),通过热熔法制备T700/603预浸料,并制备单向板。研究表明:随着w(MWCNTs-COOH)的增加,树脂基体表观固化度逐渐下降;当w(MWCNTs-COOH)低于0.50%时,MWCNTs-COOH能有效提高树脂基体及其碳纤维复合材料的力学性能;而w(MWCNTs-COOH)为1.00%时,基体及复合材料的性能出现下降。
Different contents(mass fraction 0.25%, 0.50%, 1.0%) of carboxyl multi-walled carbon nanotubes(MWCNTs-COOH) were dispersed in 603 epoxy resin. T700 carbon fiber prepared containing carbon nanotubes had been successfully produced by hot-melt method and then the laminated composites plates were prepared. The results confirmed that with the increase of MWCNTs-COOH content, the cured degree of matrix is gradually decreased. When the MWCNTs-COOH content is less than 0.5%, MWCNTs-COOH can improve the mechanical properties of the resin matrix and carbon fiber composite material;and when MWCNTs-COOH content increased to 1.0%, the properties of the matrix and the composite material are degraded.
