“…Haile et al [33] conducted fatigue tests on composite materials with Terfenol-D particles embedded between their graphite-epoxy prepreg layers and evaluated their damage-sensing capability by measuring the magnetic flux density change using a pickup coil. Additionally, other researchers have studied this SHM technology using magnetostrictive FRP composites [34][35][36][37]. Furthermore, Fe-Co alloys exhibit ductility and good workability, and new magnetostrictive epoxy composites have been developed by embedding Fe-Co fibers in epoxy resin [38][39][40].…”

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.
