Abstract: Nanostructure aluminum fiber-metal laminates are disclosed. In one embodiment, a laminate includes a nanostructure aluminum metal layer bonded to a fiber layer. In another embodiment, the nanostructure aluminum metal layer may be produced by mechanically alloying an aluminum alloy powder submerged in a liquid nitrogen solution. Alternately, a plurality of fiber layers may be disposed between a pair of nanostructure metallic layers. The laminate may be cured at optimal temperatures that do not affect the properties of the composite. In another embodiment, a hollow core may be incorporated between structure aluminum fiber-metal laminate assemblies.

Abstract: An exemplary fiber metal laminate includes at least two metallic layers and at least one fiber layer bonded between the two metallic layers. The fiber layer includes a resin matrix and organic polymeric fibers with a modulus of elasticity greater than 270 GPa. The polymeric fibers may include poly diimidazo pyridinylene fibers. The metallic layers may include pre-treated aluminum alloy layers.
