As shown by previous research results, the internal electrically conductive network, which is constructed by the contacts between conductive carbon fibers, is very important in correlating the measured electrical resistance change of CFRP composites under tensile loading to the mechanical damage state. In this study, the internal conductive network in CFRP is investigated experimentally and analytically. The anisotropy characteristics of the electrical conductivity in CFRP are measured for various carbon fiber volume fractions using DC 4 and 6 probe methods. The electrical ineffective length, which represents the internal conducting path due to the fiber contacts, is also estimated using the resistance change curve obtained by mechanical tensile tests. For the analytical investigation, Kirchhoff's rule for DC network circuit analysis is combined with the Monte Carlo simulation for the contact point distribution. By comparing the analytical and experimental results, the distribution configuration and the number of contact points, which constitute the internal electrically conductive network of CFRP composites, can be evaluated quantitatively.
