摘要：
Carbon nanotube buckypaper is a typical mesoporous material, which can be co-cured with composite materials. It can be used for real-time health monitoring of composite structures owing to the good interfacial bonding, electrical conductivity and thermal conductivity. In this paper, carbon nanotube buckypaper composites has been prepared and the self-sensing properties of bending deformation has been characterized also. The results show that the resistance change rate of carbon nanotube buckypaper sensor is consistent with that of strain gauge. The bending strain sensing coefficients of carbon nanotube buckypaper sensor on composite top surface and bottom surface are 1.4 and 1.6 respectively. These shows that carbon nanotube buckypaper sensor can be used for strain sensing and buckypaper composites has a good self-sensing property.
