In recent years, the need for long-term use of equipments and apparatus has been increasing. In relation to it, a degradation diagnostic technology has received much attention. In the present study, an internal strain measurement technique by using embedded Extrinsic Fably-Perot Interferometer (EFPI) optical fiber sensors was adopted as the degradation diagnostic method for epoxy molds and its measurement ability was investigated. In the experiments, internal strains were measured with the EFPI sensor embedded in the epoxy mold including a metal cylinder during its molding and heat cycle fatigue. From the results, it was found that the embedded EFPI sensor has abilities of internal strain measuremen during molding and crack detection under heat cycle fatigue.
