Fiber metal laminates are good candidates for advanced aerospace structural applications due to their high specific mechanical properties especially fatigue resistance. The most important factor in manufacturing of these laminates is the adhesive bonding between steel and FRP layers. In this study several glass-fiber reinforced steel laminates with different bonding adhesion were manufactured. Mechanical Tests like Tensile, Compression and Impact tests were carried out based on ASTM standard were then conducted to study the effects of interfacial adhesive bonding on impact behavior of these laminates. It is observed that the damage size is greater in laminates with poor interfacial adhesion compared to that of laminates with strong adhesion between steel and glass layers. In addition, FMLs of with good adhesion bonding shows better resistance under low velocity impact and their corresponding contact forces are about 50% higher than that of specimens with a weak bonding. Moreover, maximum central deflections in laminates with strong bonding are about 30% lower than that of FMLs with poor adhesion.
