“…The strains of the CNF–CoFe 2 O 4 composite papers were measured by an orthogonal strain gauge (JFGS-1-120-D16-16 L3M2S, Kyowa Electronic Instruments Co., Ltd., Japan) positioned on the sample surface under an applied magnetic field range of ± 733 kA/m. The data were collected by data loggers (NR-ST04 and NR-HA08, Keyence, Japan) 28 .…”

“…In addition, they are easier to manufacture to the required geometry than the above-mentioned giant magnetostrictive alloys. Previous studies on MPCs have reported terfenol-D particles 26 and galfenol particles 27 dispersed through an epoxy resin matrix (terfenol-D/epoxy and galfenol/epoxy composites, respectively), Fe–Co alloy particles dispersed through a polyurethane matrix (Fe–Co/PU composites) 28 and various others 29 , 30 . Positive magnetostriction values of 1600, 360, and 70 ppm have been reported in terfenol-D/epoxy, galfenol/epoxy, and Fe–Co/PU, respectively.…”

Polymers are often combined with magnetostrictive materials to enhance their toughness. This study reports a cellulose nanofibril (CNF)-based composite paper containing dispersed CoFe2O4 particles (CNF–CoFe2O4). Besides imparting magnetization and magnetostriction, the incorporation of CoFe2O4 particles decreased the ultimate tensile strength and increased the fracture elongation of the CNF–CoFe2O4 composite paper. CNF was responsible for the tensile properties of CNF–CoFe2O4 composite paper. Consequently, the magnetic and magnetostrictive properties and tensile properties of CNF–CoFe2O4 composite paper can be controlled by changing the mixture ratio of CNF and CoFe2O4 particles.

“…Kurita et al fabricated a soft composite by randomly dispersing Fe-Co-V alloy particles in a polyurethane matrix, and magnetic flux changes were caused by the magnetoelastic effect. 211 The fabricated soft composite induced a magnetoelastic effect when subjected to a bending load. An approximately 0.05 mT change in magnetic flux was measured using a Hall sensor positioned at the bottom of the composite.…”

“…Their application to sensors and energy harvesting devices is being considered, as with magnetostrictive materials. [12][13][14] Katabira et al [15] fabricated magnetostrictive composites incorporating FeCo fiber/polyster fabric and investigated their sensor performance. In their article, it was indicated that the change in magnetic flux-density due to deformation is related to the magnetization of the FeCo fiber and the bias magnetic field.…”

Here, we experimentally and theoretically examined the fastening characteristics and internal axial force of magnetostrictive composite bolts using magnetic flux‐density change. Magnetostrictive composite bolts were fabricated using FeCo wire and epoxy resin by applying magnetic field and preload. The advantage of using a bolt made of magnetostrictive composite materials is that it will have reduced weight and can be applied to prestress. Tightening tests were conducted, with and without external‐bias magnetic fields, to measure bolt strain and magnetic flux‐density change. Then, theoretical and finite element analyses were performed to calculate the strain, axial force, and magnetic flux‐density. Theoretical results were compared with experimental results to determine the relationship between tightening torque, internal axial force, and magnetic flux‐density change. We found that the applied magnetic field and preload conditions during fabrication, as well as the bias magnetic field during the tightening tests, have a significant effect on the magnetic flux‐density change of magnetostrictive composite bolts. The results of this study help propose new possibilities for internet of things and structural health monitoring nodes.This article is protected by copyright. All rights reserved.
