METAL BASE CARBON FIBER COMPOSITE MATERIAL AND PROCESS FOR PRODUCING THE SAME

Title:

METAL BASE CARBON FIBER COMPOSITE MATERIAL AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2005/059194

Kind Code:

A1

Abstract:

A process in which while inhibiting the formation of metal carbide, there is produced a metal base carbon fiber composite material that is lightweight, having high thermal conductivity and that is capable of control of the direction of heat current. There is provided a process for producing a metal base carbon fiber composite material, comprising the step of performing physical mixing of carbon fibers and metal powder to thereby obtain a metal fiber mixture; the step of charging the metal fiber mixture, while effecting alignment thereof, in a jig; and the step of arranging the jig in the atmosphere, vacuum or an inert atmosphere and passing direct pulse current through the jig under pressure to thereby induce heat generation by which the metal fiber mixture is sintered. In this stage, the composite material contains 10 to 80 mass% of carbon fibers based on the total mass of composite material and is sintered up to 70% or more of the ideal density.
