Although an electrical-resistance-change method is useful for monitoring delamination cracking of Carbon Fiber Reinforced Plastics (CFRP) laminates, the method requires a lot of experiments or FEM analyses to obtain relationship between the electrical resistance changes and delamination cracking. In the previous studies, the author proposed the anisotropic electric potential function to analyze electric current density of CFRP laminates. The function was applied to thick CFRP laminates. In the present study, the method is expanded to thin CFRP laminates using an image method. The number of images is determined using the electric current analysis of thick CFRP laminates here. Electric potential changes caused by delamination cracking can be calculated using anisotropic doublet line. The anisotropic doublet method is applied here to calculate the electric voltage change at the surface of a thin CFRP laminate and the results are compared with FEM analysis. As a result, the method is shown to be very effective.
