Patent ID: 8304090

Claim:
A three dimensional composite sheet having first and second major surfaces defined by a first and second dimension of the composite sheet and a thickness defined by a third dimension extending between the first and second major surfaces of the composite sheet, the major surfaces defining outermost boundaries of the composite sheet that are externally disposed, the composite sheet having a first material and a second material which combine to give the composite sheet a compressive strength that is higher than a compressive strength of the second material and a thermal conductivity that is higher than a thermal conductivity of the first material, said composite sheet comprising: a first major surface area defining at least a first portion of the first major surface which includes the first sheet material arranged in a first array of shapes in said first portion of the first major surface surrounded by the second sheet material, the first sheet material for primarily withstanding a compressive force substantially normal to the first major surface and the second sheet material for primarily conducting heat; and a second major surface area defining at least a second portion of the second major surface which includes the second material arranged in a second array of shapes on said second portion of the second major surface surrounded by the first sheet material, where the first sheet material extends completely through the thickness of the composite sheet to extend the first array of shapes from the first major surface to the second major surface, and the second sheet material extends completely through the thickness of the composite sheet to extend the second array of shapes from the second major surface to the first major surface.
