The Fiber Reinforced Plastics (FRP) is widely utilized by making the best of features of lightweight and high strength and high corrosion resistance. Various immersion tests were carried out in order to obtain the corrosion resistance data of FRP until now. However, this research is only to mention to water absorption quantity and degradation of glass fiber as the causes of strength degradation by the chemicals, and has not clarified region and route of water absorption. Therefore, the reliability is lacking on these evaluations for the material degradation. So, we proposed the new evaluation method for the degradation that applied X-ray analysis microscope. It aims at improvement of reliability of the FRP material by the new evaluation method.
