Metal-fiber reinforced resin matrix composites formed by combining metals with fiber reinforced polymers(FRP) represent a new generation of lightweight, multifunctional materials demonstrating significant application potential in aerospace, new energy vehicles, and high-end equipment manufacturing. The interfacial bonding state of this composite is the core factor determining its superior mechanical properties. However, issues such as insufficient wettability between metal and resin matrix, weak chemical bonding interactions, high thermal residual stresses due to differing thermal expansion coefficients, and interfacial debonding failure under thermo-mechanical coupled loads severely limit stress transfer efficiency between cross-scale heterogeneous materials and compromise long-term structural reliability. Interface modification techniques, such as metal surface treatment and functional layer introduction, can significantly enhance the interface bonding strength, stress transfer efficiency, and durability between metals and FRP composites, thereby optimizing the overall performance of composite structures. This paper systematically reviews key technologies and research progress in metal-FRP interface modification and outlines future development trends.
