Abstract:
1. A carbon-based composite material comprising: a graphite substrate having a surface; and a carbon-based sheet having a first surface adhered to the surface of the graphite substrate with a heat-resistant adhesive, the carbon-based sheet having grooves, wherein the carbon based sheet is not divided into separate sheets by the grooves, wherein the carbon-based sheet has a second surface that is planar and is opposite the first surface, wherein the grooves extend from the second surface within the carbon-based sheet toward the first surface, and the grooves do not extend from the second surface to the first surface, wherein at least one first groove extends linearly in a first direction along the second surface, wherein at least one second groove extends linearly in a second direction along the second surface, the second direction being substantially perpendicular to the first direction, wherein the at least one first groove and at least one second groove do not intersect with each other, and wherein the carbon-based sheet comprises an expanded graphite sheet.
