Self- Diagnosis of Damage in Hybrid FRP Reinforced Concrete
하이브리드 FRP보강근 콘크리트의 손상 자가진단

Abstract
For giving self-diagnosing capability, a method based on monitoring the changes in the electrical resistance of hybrid FRP reinforced concrete has been tested. Then after examining change in the value of electrical resistance of carbon fiber in CFRP, CFGFRP, CFAFRP and e.t.c., before and after the occurrence of cracks and fracture in hybrid FRP reinforced concrete at each flexural weight-stage, the correlations of each factors were analyzed. As the results, it is clarified that when the carbon fiber tows fracture, the electrical resistance of it increase largely, and afterwards hybrid FRP composites can be resist the load due to the presence of the reinforced fiber, for example, glass fiber or aramid fiber tows.
