Abstract

The paper discusses a method for measuring changes in the electric resistance of a unidirectional carbon-fiber-reinforced plastic (CFRP) to detect an internal delamination. A numerical solution was obtained by the four-probe method for measuring the electric resistance. The influence of distance between electrodes on the efficiency of delamination detection was investigated. The problem was solved by the method of planning of experiments and constructing a surface response by using a 2D finite-element model. The distance between electrodes and the length of delamination were selected as parameters of the study. Distances between the internal and external electrodes for an effective detection of delaminations are determined.
