Experimental study on the effect of stacking sequence of layers in the fiber metal laminates subjected to static and dynamic tests

In the recent years, in several engineering applications, the traditional materials like steel or metal alloys are widely used together with composite materials to obtain hybrid structures. Fiber metal laminates (FMLs) are considered as an important type of these hybrid structures. In the present paper, experimental study was performed in order to investigate the mechanical properties of FMLs subjected to standard static and dynamic loading conditions. The FMLs are made of three and five alternative layers of 430 stainless steel sheets and glass fiber prepreg reinforced composite (G10). The specimens were subjected to tensile, flexural and impact tests according to ASTM standards. The effect of stacking sequence of the layers on the mechanical properties of the resulting FML, are experimentally investigated. The experimental results revealed that the stacking sequence has a significant effect on the mechanical properties of FMLs.
