摘　　要：由于碳纳米纸与复合材料具有良好的界面结合性能,以及良好的导电导热性能,因此可以被用于复合材料的全寿命健康监测.本文制备了碳纳米纸及其传感器,以及在不同位置嵌入碳纳米纸传感器的复合材料,并进行拉伸加载卸载测试.获得了碳纳米纸传感器电阻变化率随传统应变片测得的复合材料层合板应变的变化趋势,拟合得到了碳纳米纸传感器的应变传感系数,阐明了复合材料在变形时的协同性,证明了碳纳米纸传感器可以用于复合材料的拉伸疲劳损伤监测.As carbon nanotube buckypaper composites have a good interfacial properties,conductivity,and thermal conductivity,they can be used for whole-life health monitoring of composite materials. In this paper,carbon nanotube buckypaper and its sensors have been prepared. Meanwhile,composites samples with the buckypaper sensors at different positions were obtained. Tensile loading and unloading tests were performed. By analyzing changes in the buckypaper resistance change rate and composite strain,a strain-sensing coefficient was obtained to clarify the synergistic deformation of composite materials. The results of this study demonstrate that buckypaper sensor can be used to monitor the tensile fatigue damage of composites.
