In the present study, the electrical resistance change behavior of CFRP laminate [±25/±25/90]s under re/unload loading condition is investigated experimentally. Especially, the effect of the delamination on the electrical characteristics is evaluated using the internal and the surface electrical voltage distrbution. From the experimental results, we identified that the residual resistance reduces along with the increase of the previously applied maximum strain and the internal voltage distribution in thickness direction does not change despite of the delamination. Voltage distribution of the bottom and the top surface indicates that the electrical current can flow through the region that has no delamiation and this can explain the constant internal voltage distribution in thickness direction. For the reason of the decrease in the residual resistance, further theoretical and experimental investigations are needed
