Patent ID: 7955713

Claim:
A structure comprising: a laminate including at least a first metal layer having a thickness of at most about 0.8 mm, at least a second metal layer having a thickness of at most about 0.8 mm, and a fiber-reinforced polymer layer having a fiber volume content of at least about 50% therebetween; at least one upper metal layer connected to a top of the laminate and having a constant thickness of at least about 1.0 mm; and at least one lower metal layer connected to a bottom of the laminate and having a constant thickness of at least about 1.0 mm, wherein the at least one upper metal layer connects to the laminate by a first fiber-reinforced polymer layer having a fiber volume content not exceeding about 45%, and wherein the at least one lower metal layer connects to the laminate by a second fiber-reinforced polymer layer having a fiber volume content not exceeding about 45%.
