For the safe operation of glass‐fiber‐reinforced polymer (GFRP) laminates, evaluating the applied stress and the health of composite structures is crucial. Magnetostrictive materials are functional materials that can be applied to structural health monitoring as sensor materials. Herein, a method for detecting whether the maximum stress of GFRP laminates under bending exceeds the allowable stress using magnetostrictive fibers is proposed. First, magnetostrictive Fe–Co alloy fibers are embedded in GFRP laminates. Then, four‐point bending tests are conducted. Magnetomechanical coupled modeling based on the composite beam theory is then applied to the experimental results. The effects of the position of Fe–Co fibers on the magnetostrictive behavior and mechanical properties of the prepared composites are evaluated. A concept for monitoring the relationship between the maximum bending stress and the allowable stress of the composite materials is proposed.

Present research on TiNiSi-type MnCoSi-based alloys focuses on finding a suitable doping element to effectively reduce the critical magnetic field (μ0Hcri) required to induce a metamagnetic transition. This paper provides a guide to achieve this goal through an experimental investigation of Mn1-xPtxCoSi and MnCo1-xPtxSi alloys. In Mn1-xPtxCoSi, as x increases, μ0Hcri at room temperature decreases, while in MnCo1-xPtxSi, it increases. This phenomenon can be attributed to the fact that larger Pt atoms prefer Co sites over Mn sites, as predicted by our density-functional theory. Consequently, in Mn1-xPtxCoSi, larger Co atoms are extruded into the Mn atoms chain, increasing the nearest Mn-Mn distance and resulting in a reduced μ0Hcri. This finding suggests that transition-metal atoms with more valence electrons preferably occupy the Co site, while those with fewer valence electrons preferably occupy the Mn site. Adhering to this rule, one can easily obtain a low μ0Hcri and large magnetostrain under a low magnetic field by selecting a suitable foreign element and chemical formula, as demonstrated by the Mn1-xPtxCoSi alloy.

“…In recent years, significant progress has been made in the application of magnetostrictive composites and structures [18], such as magnetostrictive fibers, polymers, and so on [19,20]. This may lead to changes in material properties [21,22]. Fusing magnetostrictive powder into polymer improves the mechanical properties of the resulting composite structure, but often results in a discontinuity in the inverse magnetostrictive properties [23,24].…”

Encapsulation of magnetostrictive alloy wires in epoxy resin has great potential for energy harvesting and can be applied to energy harvesting in human motion. In this work, a magnetostrictive wire-epoxy resin arch composite structure was proposed for harvesting energy generated by foot motion. A prestress was introduced during the resin curing process, and the relationship between the output voltage and material properties was derived based on the Villari effect. Three kinds of Fe-based magnetostrictive wires were prepared and their magnetic properties were measured, then a prototype single-layer arch composite structure was fabricated and an experimental platform was built for testing, and the amplitude of the output open-circuit voltage could reach 936 mV under an impact pressure of 750 N, which proved that the Fe–Ga alloy composite structure was superior to Fe–Co and Fe–Ni alloys in energy harvesting. The double-layer arch-shaped Fe–Ga composite structures energy harvesting prototype outputs a maximum voltage of up to 940 mV in foot energy harvesting experiments, and collected a maximum power of up to 2.45 mW at a step frequency of 3.5 Hz. Consequently, this work emphasized the feasibility of magnetostrictive alloy-epoxy composite structures for energy harvesting in human motion and the potential for developing new ways of energy harvesting.
