METAL-GRAPHITE COMPOSITE MATERIAL HAVING HIGH THERMAL CONDUCTIVITY AND METHOD FOR PRODUCING THE SAME |
摘要 |
<p>The present invention provides a metal-graphite composite material favorable to two-dimensional diffusion of heat and having a high thermal conductivity in two axial directions, and a production method therefor. The metal-graphite composite material of the present invention includes: 20 to 80% by volume of a scaly graphite powder; and a matrix selected from the group consisting of copper, aluminium and alloys thereof, wherein the scaly graphite powder in which a normal vector to a scaly surface thereof is tilted at 20° or higher with respect to a normal vector to a readily heat-conducting surface of the metal-graphite composite material is 15% or less relative to a whole amount of the scaly graphite powder, and the metal-graphite composite material has a relative density of 95% or higher.</p> |
