With the rapid development of aerospace equipment in China, new requirements have been put forward for the comprehensive properties and lightweight of the materials used in the structural parts in the above fields. In the past decades, the market demand for large passenger aircraft has been expanding, which has stimulated the rise of new materials, and made materials develop towards high strength and light weight. The fiber metal laminate is an interlayer hybrid composite material made of aluminum alloy and fiber prepreg. Fiber metal laminates combine the excellent properties of metal and composite materials, with low density, excellent damage tolerance, impact resistance and fatigue performance, and have attracted more and more attention in the aerospace and rail transit fields. At present, most of the metal fiber laminates (FMLs) used in commercial production are mainly ARALL based on aramid fibers and glass reinforced aluminum laminates(GLARE) laminates based on high-strength glass fibers. This paper summarizes the preparation process of fiber metal laminates, summarizes the test methods of mechanical properties such as bending test, tensile test, impact test and fatigue test, and explores the development of new fiber metal laminates in the future so as to provide reference information for the development of fiber metal laminates.
