Abstract
Structural health monitoring of composite materials has always been a hot topic for researchers at home and abroad. Compared with traditional sensors for monitoring damage, fiber Bragg grating (FBG) sensors have the advantages of being free from electromagnetic interference, light weight, small size, and non-corrosion resistance. Therefore, FBG sensors are widely used in the structural health monitoring of composite materials. This paper briefly describes the structure and principle of FBG sensor, analyzes the application status of FBG sensor in the field of composite structure health monitoring at home and abroad, explains the good performance of FBG sensors in the health monitoring of composite structures and introduces the related neighborhood research benefits; Finally, it is based on FBG Sensor composite health monitoring technology is summarized and forecasted.
