The interfacial strength is especially the important property amongst the other components', reinforcing fiber and matrix which consist of PMC. For the further use in industrial application, the evaluation of interfacial strength under dynamical loading is requested. In this study, we conducted the tensile test on SFC specimen and observation of nucleation of interfacial debonding at different strain rates, and recognized the dependency of interfacial strength on strain rates. According to elasto-plastic analysis with the assumption that matrix's yield stress be the variant of strain rates, stress distribution of the interface asymptotically approaches the elastic analysis, and it can be concluded that the dependency of interfacial strength on strain rates caused by matrix's dependency on strain rates.
