摘要

Fiber metal laminates (FMLs) are hybrid composite materials having superior properties of both composite materials and metal alloys. FMLs are initially developed to enhance the fatigue properties under in-plane loading conditions. In the past three decades extensive research has been carried out which has led to enhancement of the specific properties of FMLs, such as improved damage-tolerance to fatigue crack growth, improved specific strength, high off-axis tensile properties, high toughness, corrosion and fire resistance. With these added advantages, particularly high strength to weight ratio, FMLs are promising materials in the aircraft structure. In the recent years scope of using FMLs in industrial applications has been gaining significant research interest toward improvement of various aspect of FMLs. Extensive research has been done to understand the performance of FMLs under low/high velocity impact loads, fatigue loads, in-plane loads and off-axis loads, to extend the application of FMLs to the various parts of aeronautical structure and automotive components. More studies are required to understand the static and dynamic response of FMLs under various boundary conditions and width to length ratios.
