The fiber metal laminate composites a new generation of hybrid composites that have high strength to weight ratio. Good mechanical properties combining the properties of metals and fiber composites, led to the widespread use of composites in the industry, especially the aviation industry find. Add shape memory alloy to fiber metal laminate composite, due to super elasticity properties of alloy, makes the alloy formed during the impact hysteresis loop, will attract a lot of energy and impact properties of the fiber metal laminate composites increased. In this study, effects of different strains of nickel-titanium shape memory alloy wire high temperature, experimental in this type of composites against low speed impact using the impact falling, investigated. In metal part of fiber metal laminate composites, 2024-T3 aluminum alloy sheet and in composite part of glass fibers and epoxy resin is used. 6 wires with the pre strains 1, 2 and 3% in order to wrapping in the fibers metal laminate composites, was used. Increase the impact resistance of such composites by increasing pre strain as well as the energy absorbed by the shape memory alloy when impact, the results of this research was.
