The present paper addresses the correlation between the mechanical damage behavior and the change of electrical resistance of CFRP under tensile loading. The linear relation between the strain and the electrical resistance of carbon fiber is obtained experimentally and the CFRP's electrical behavior under tensile loading is investigated. The mechanical damage evolution process is studied using the Global Load Sharing (GLS) model and correlated to the electrical behavior. These investigations leads to a new concept of electrical ineffective length and the electrical model using the DC series circuit with equally spaced discrete parallel cells is proposed to apply the electrical circuit theory to real composites. The predicted results using this model explain the experimental results very well.
