Composite thermal interface objects

A composite thermal interface object comprising:

• a first layer partially covering a heat producing device, the first layer comprising a first silicone polymer having a first elastic modulus, and first graphite fibers aligned in a direction that is substantially orthogonal to a surface of the first layer, wherein the first graphite fibers are arranged in concentrated graphite fiber columns, each column having a height substantially equal to a thickness of the first layer, each column being uniformly spaced apart from adjacent columns;
• a second layer comprising second graphite fibers, zinc oxide, and a second silicone polymer having a second elastic modulus different from the first elastic modulus;
• and
• a third layer comprising third graphite fibers, the third layer having a third elastic modulus different from the first elastic modulus,
• wherein:
• at least one surface of the second layer has curvature, wherein the curvature of the surface of the second layer corresponds to an inverse curvature of the heat producing device, and at least one surface of the third layer has curvature, wherein the curvature of the surface of the third layer corresponds to an inverse curvature of a heat dissipation device, wherein the composite thermal interface object comprises an hourglass shape,
• the first layer being located between the second layer and the third layer, at least one of the second graphite fibers or the third graphite fibers are not aligned in a direction parallel to the direction of the first graphite fibers,
• the composite thermal interface object has a thickness of from 0.25 mm to 5 mm, a ratio of a first thickness of the first layer to a second thickness of the second layer is from 1:1 to 10:1, and the first graphite fibers constitute from 3 wt% to 20 wt% of the first layer.
