Effect of Shape Memory Alloy Wire on High Velocity Impact Resistance of Smart Fiber Metal Laminate Composite

Fiber metal laminates are now very widely used in advanced industries such as the aerospace industry. After introduction of thesematerials, researchers had successfully overcome the disadvantages of metals like corrosion,composites materials such as lowimpact resistance. They combined advantages of metals,composites,used them in a hybrid structure simultaneously. One ofthe most important loading which a fiber metal laminate in aerospace industry is faced, is high velocity impact loading. In this study,it had been tried to increase impact resistance of fiber metal laminates using the exceptional properties of shape memory alloys.Therefore, nickel-titanium shape memory alloy wires are embedded between layers of basalt fiber reinforced epoxy composite andthese layers are entirely covered by two sheets of aluminum type 6061 in top,bottom. The results of high velocity impact testsindicate that by embedding wires, the energy absorbed by the sample,subsequently fracture resistance increases significantly,However, increasing the number of wires does not have significant effect on energy absorption,impact resistance of structure.
