하이브리드FRP 탄소계 리브 및 탄소섬유시트 보강 콘크리트의 자가진단 기능 검토

Self-diagnosis property of strengthened concrete by rib of hybrid FRP and carbon fiber sheet

For giving self-diagnosing capability, a method based on monitoring the changes in the electrical resistance of carbon materials in strengthened concrete has been tested. Then after examining change in the value of electrical resistance of carbon materials used as a rib of CFGFRP or a sheet of carbon fiber before and after the occurrence of cracks and fracture in hybrid FRP or carbon fiber sheet strengthened concrete at each flexural weight-stage, the correlations of each factors were analyzed.
