Abstract
In this study, the electrical resistance change behavior of CFRP laminate [±25/±25/90]s under re/unload loading condition was investigated. Especially, the effect of the delamination on the electrical characteristics was evaluated using the internal and the surface electrical voltage distribution. From the experimental results, we identified that the internal voltage distribution in thickness direction does not change despite of the delamination, because the voltage distribution of the bottom and the top surface indicates that the electrical current can flow through the region that has no delamination. And for further theoretical investigation, DC network circuit of CFRP using discrete Kirchhoff-Monte Carlo model was examined in section3.
