“…With respect to the low dimensionality and excellent properties, it is intriguing to use metallic glass fibers (MGFs) as fillers to improve the mechanical performance of composites [20][21][22]. In addition, magnetically soft MGFs show giant magnetoimpedance (GMI) [23][24][25] and apparent permeability relaxation under electromagnetic excitations [26][27][28]. The MGF-reinforced composites can potentially be used as functional materials, such as electromagnetic interference filters and microwave absorbers [26][27][28].…”

Optimizing the mechanical properties of composites through microstructural design has been a long-standing issue in materials science. In this study, we reinforced a typical polymer, i.e., polyethylene-terephthalate-woven fabric, with a type of Fe-based metallic glassy fiber (MGF) with an extremely large Young’s moduli. The MGF-reinforced fabrics, with three different fiber bundle orientations (0°, 45°, and 90°), were investigated by in situ electron-microscopy mechanical testing techniques in conjunction with a digital image correlation (DIC) technique. The fabrics exhibited a pronounced anisotropic mechanical response, and the associated characteristics were verified to depend on the fiber bundle orientation relative to the external load. Furthermore, localized strains near the intersections of the fiber bundles were found to be much higher than the global strain. It is confirmed that the restriction from warp to weft is the dominant factor influencing strain localization during deformation. Our results are enlightening for understanding the fracture mechanisms of composites.
