摘要

摘要: 由于碳納米紙與復合材料具有良好的界面結合性能,以及良好的導電導熱性能,因此可以被用于復合材料的全壽命健康監測.本文制備了碳納米紙及其傳感器,以及在不同位置嵌入碳納米紙傳感器的復合材料,并進行拉伸加載卸載測試.獲得了碳納米紙傳感器電阻變化率隨傳統應變片測得的復合材料層合板應變的變化趨勢,擬合得到了碳納米紙傳感器的應變傳感系數,闡明了復合材料在變形時的協同性,證明了碳納米紙傳感器可以用于復合材料的拉伸疲勞損傷監測.

Abstract: 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.
