针对纤维增强树脂基单向复合材料横向刚强度低的问题,通过碳纳米管(CNTs)在单向复合材料横向方位取向控制技术研究,建立了一种CNTs在树脂基复合材料中电场取向装置,制备了取向CNTs/环氧树脂(EP)复合材料及取向CNTs/玻璃纤维(GF)增强环氧树脂基单向层合板,并对不同电场强度、CNTs含量对其力学性能的影响进行了试验分析.结果表明,施加300V/cm的取向电场时,添加0.2wt％多壁碳纳米管(MWNTs)/EP储能模量较未添加MWNTs时提高了68.42％,较随机方位分布MWNTs/EP提高了1.36％;取向MWNTs/GF增强单向层合板横向弯曲强度及模量比未添加MWNTs时分别提高了72.2％和92.1％,比随机方位分布MWNTs增强时分别提高了58.29％和61.43％;施加439V/cm的取向电场时,添加0.2wt％取向MWNTs/GF增强单向层合板横向弯曲强度及模量比未添加MWNTs时分别提高了64.7％和63％,比随机方位分布MWNTs增强时分别提高了51.42％和36.90％,取向CNTs/GF增强树脂基单向层合板横向刚强度均得到了大幅提高.
