| Abstract: | Direct current (DC) electrical resistance measurement is effective for studying the interfaces in fibrous composite materials, particularly carbon fiber composites, which are electrically conducting. The measurement yields information on the fiber–matrix interface, residual stress, and interlaminar interface, and can be made in real time during debonding, residual stress reduction, temperature change, and interlaminar shear. This paper reviews the methods and applications in relation to polymer–matrix and cement–matrix composites. |
