采用正压过滤法制备了多壁碳纳米管(MWCNTs)网格(巴基纸),并采用真空辅助RTM工艺制备了MWCNTs网格/环氧树脂复合材料.通过SEM、FTIR、拉伸测试等对MWCNTs网格的微观形貌和性能进行了表征,并研究了MWCNTs网格/环氧复合材料的拉伸性.结果表明,所制备的功能化MWCNTs网格比较均匀,拉伸强度在22～32 MPa之间,拉伸模量约为1 GPa,相比未功能化处理的MWCNTs网格,强度最大提高了约167％.功能化MWCNTs网格/环氧树脂复合材料的拉伸强度和拉伸模量可达到152 MPa和6.48 GPa,相比空白环氧树脂提高了约1倍以上,拉伸试样断面SEM表明,环氧树脂对功能化MWCNTs网格的浸润效果良好,界面结合紧密,有效地提高了复合材料的力学性能.
