【 摘 要 】

The fiber Bragg grating (FBG) sensing technique was introduced to research the real-time corrosion monitoring method for the simulation structures of aircraft during an accelerated corrosion test. The results showed that the variation of grating wavelength was able to describe the corrosion damage caused by corrosion at different times. The relationship between the corrosion damage and the variation of central grating wavelength in the process of accelerated corrosion is established.
