THE DEVELOPMENT OF STRUCTURAL HEALTH MONITORING FOR CFRP COMPOSITE BY ELECTRICAL RESISTANCE METHOD

The changes in electrical resistance of carbon fiber reinforced polymer (CFRP) composites, which are conductive, was described in real time monitored by d.c and a.c electrical resistance measurement under different mono, cyclic loading conditions. The changes in electrical resistance of CFRP composites are related to the changes in the microstructure in the materials. It is expected to monitoring CFRP structure health and make electrical resistance method be an intrinsically intelligent self-diagnosing technique.
