제목 Crack detection in concrete structures by using CP-GFRP/GFRP smart sensor
초록  In this paper were studied detection function of CP-GFRP/GFRP composites with self-diagnosing function for preventing fatal fracture of concrete structures. The changes in electrical resistance strain, and a tremendous change was observed at the transition point where carbon fiber tows were broken. Therefore, the composites are not to monitor damage from the early stage. On the other hand, the change in electrical resistance of CP-GFRP/GFRP composites increased almost linearly in proportion to strain. The self-diagnosis ability of the composites enabled the detection of micro-crack formation and propagation in concrete structures.
