“…; validation, T.M. GFRP is often used at cryogenic temperatures [11], and Fe-Co fibers do not lose their magnetostrictive properties, even at cryogenic temperatures [63], making them a good match for cryogenic applications. In previous studies, fibers with diameters of 1 [39] and 0.2 mm [38] were used, although fibers with a 0.05 mm diameter were used in this study, and they were useful as they did not reduce the GFRP strength.…”

As sensor materials for structural health monitoring (SHM, a nondestructive test for the continuous evaluation of the conditions of individual structural components and entire assemblies), magnetostrictive materials, piezoelectric materials, and optical fibers have attracted significant interest. In this study, the mode I interlaminar fracture load and crack self-detection potential of glass fiber-reinforced polymer (GFRP)–embedded magnetostrictive Fe–Co fibers were investigated via double cantilever beam testing. The results indicated that by controlling the amount of Fe–Co fibers introduced into GFRP, the number of Fe–Co fibers could be reduced without compromising the performance of GFRP. Furthermore, the magnetic flux density increased significantly with crack propagation, indicating that the magnetic flux density change could determine crack propagation.
