Laminate structures and methods for forming same are disclosed. In one embodiment, a laminate structure includes a metal-polymer composite lamina. The metal-polymer composite lamina has a first face and a second face spaced apart, and extends to a terminal edge. The lamina includes a ply of fiber-reinforced polymer that extends between the first face and the second face and has an interior edge. The interior edge defines at least one cutout. A ply of metal foil extends between the first face and the second face substantially from the interior edge filling the at least one cutout.

What is claimed is: 1. A laminate structure, comprising: a first region having a non-uniform thickness, the first region including: a first layer having: a first portion of a non-metallic material, the first portion at least partially encompassing a cutout region; a second portion of a metallic mat
What is claimed is: 1. A laminate structure, comprising: a first region having a non-uniform thickness, the first region including: a first layer having: a first portion of a non-metallic material, the first portion at least partially encompassing a cutout region; a second portion of a metallic material formed within the cutout region, the second portion abutting the first portion; a second layer adjacent the first layer that non-interruptably extends along the first layer, the second layer being formed from a non-metallic material; and a third layer having a first portion of a non-metallic material, the first portion at least partially encompassing a cutout region, and a second portion of a metallic material formed within the cutout region, the second portion being co-planar with the first portion, and wherein the second layer is disposed between the first and third layers. 2. The laminate structure of claim 1, wherein the first portion includes a fiber-reinforced polymeric material. 3. The laminate structure of claim 1, wherein the first portion includes a fiber-reinforced polymeric material having one or more fibers formed from a material selected from a group consisting of aramids, polyolefins, glass, carbon, boron, and ceramics, and wherein the metallic material of the second portion is formed from a material selected from a group consisting of titanium, aluminum, alloys of titanium, alloys of aluminum, and alloys of iron. 4. The laminate structure of claim 1, further comprising a second region integrally coupled to the first region by one or more layers of non-metallic material, the first layer of the first region not extending into the second region. 5. The laminate structure of claim 4, wherein the first region includes a minimum-thickness portion, the second region being integrally coupled to the minimum-thickness portion and having a thickness approximately equal to the minimum thickness portion of the first region. 6. The laminate structure of claim 4, wherein the second region consists essentially of one or more non-metallic layers. 7. The laminate structure of claim 4, wherein the second region consists essentially of one or more non-metallic layers. 8. A laminate structure comprising: a first region having a non-uniform thickness, the first region including: a metal-polymer lamina, the metal-polymer lamina having a first face and a second face spaced apart from the first face, extending to a terminal edge, the lamina including: a ply of fiber-reinforced polymer extending between the first face and the second face and having at least one interior edge, the interior edge defining at least one cutout; a ply of metal foil extending between the first face and the second face substantially from the interior edge to fill the at least one cutout; and a polymer lamina adjacent the metal-polymer lamina, the polymer lamina having a third face and a fourth face spaced apart from the third face, the polymer lamina including a ply of fiber-reinforced polymer that extends between the third face and the fourth face and extends non-interruptably along the metal-polymer lamina and substantially to the terminal edge. 9. The laminate structure of claim 8, wherein the metal-polymer lamina further includes a periphery and the terminal edge further defines the at least one cutout abutting the periphery. 10. The laminate structure of claim 8, wherein the metal-polymer lamina further includes an interior, the interior edge defining the at least one cutout within the interior. 11. The laminate structure of claim 8, wherein the fiber-reinforced polymer includes a fiber selected from a group consisting of aramids, polyolefins, glass, carbon, boron, and ceramics. 12. The laminate structure of claim 8, wherein the metal foil includes a metal selected from a group consisting of titanium, aluminum, alloys of titanium, alloys of aluminum, and alloys of iron. 13. The laminate structure of claim 12, wherein the alloys of titanium are selected from a group consisting of (Ti-6Al-4V), (Ti-15V-3Cr-3Sn-3Al) and (Ti-15Mo-3Al-3Nb). 14. The laminate structure of claim 8, further comprising a second region integrally coupled to the first region by one or more layers of non-metallic material, the metal-polymer lamina of the first region not extending into the second region. 15. The laminate structure of claim 8, wherein the first region includes a minimum-thickness portion, the second region being integrally coupled to the minimum-thickness portion and having a thickness approximately equal to the minimum thickness portion of the first region. 16. The laminate structure of claim 8, wherein the second region consists essentially of one or more non-metallic layers. 17. The laminate structure of claim 8, wherein the metal polymer lamina is a first metal-polymer lamina, the laminate structure further comprising a second metal-polymer lamina coupled to the first metal-polymer lamina. 18. The laminate structure of claim 17, wherein the laminate structure further comprises the adhesive resin interposed between the first metal-polymer lamina and the second metal-polymer lamina to adhesively fuse the first metal-polymer lamina to the second metal-polymer lamina. 19. The laminate structure of claim 18, wherein the first metal-polymer lamina has a first interior edge and the second metal-polymer lamina has a second interior edge and the first interior edge is not co-terminous with the second interior edge. 20. The laminate structure of claim 8, wherein the laminate structure further comprises the metal-polymer lamina and metal foil lamina, the metal foil lamina having a fifth face and a sixth face spaced apart from the fifth face and including: a ply of metal foil extending between the fifth face and the sixth face. 21. The laminate structure of claim 20, wherein the laminate structure further comprises the adhesive resin uniformly interposed between the metal-polymer lamina and the metal lamina to adhesively fuse the metal-polymer lamina to the metal lamina. 22. A laminate structure comprising: a first region having a non-uniform thickness, the first region including: a metal-polymer lamina, the metal-polymer lamina having a first face and a second face spaced apart from the first face, extending to a terminal edge, the lamina including: a ply of fiber-reinforced polymer extending between the first face and the second face and having an interior edge, the interior edge defining at least one cutout; and a ply of metal foil extending between the first face and the second face substantially from the interior edge to fill the at least one cutout; a fiber-reinforced polymer lamina, the polymer lamina having a third face and a fourth face spaced apart, extending to the terminal edge, the lamina including: a ply of fiber-reinforced polymer extending non-interruptably along the metal-polymer lamina and substantially to the terminal edge; and an adhesive resin interposed between the metal-polymer lamina and the fiber-reinforced polymer lamina to adhesively couple the metal-polymer lamina to the fiber-reinforced polymer lamina. 23.
