摘要

—Intelligent hybrid reinforced plastics (IHFRP) with fiber Bragg grating (FBG) sensors embedded in the HFRP were produced in-situ. The FBG/HFRP interface bonding is discussed. Experimental results show that the interfacial bonding of FBG/HFRP is good, which ensures that it can transfer the external load to the FBG sensor well. The novel IHFRP has a higher strain-testing precision compared to the existing products, which is necessary due to the requirements of staying cables. The survival rate of the FBG sensor is high due to the packaged sensor used during the manufacturing process. In addition, a simple and theoretical model to estimate shear and peel-off stress is proposed. According to the simulation results, the maximum shear and peel-off stress are located at the ends of the FBG sensor, and this stress is less than the strength of interfacial adhesion of the matrix material. Moreover, the larger the diameter of the packaged sensor is,the more is the additional stress induced.
