| Research Abstract |
Self-sensing method is focused on here. In the present study, statistical monitoring method is applied for the electrical resistance changes of several segments before and after the Joule heating. After Joule heating, electrical resistances of several segments are measured. Using the statistical similarity tests, the damaged area of the CFRP is detected. The method is applied to the CFRP plates here. Impact load tests were performed and damage at the electrode was also performed here. The method is experimentally proved to be effective for the detection of the delamination cracks.
