Abstract
A method for producing a composite having graphite fibers in a matrix of copper/copper alloy. The graphite fibers are coated with a refractory metal which both protects the graphite fibers from the molten copper/copper alloy while also acting as a wetting agent on the graphite fibers for intimate infiltration by the molten copper/copper alloy. The coated graphite fibers are prepared in a structure and placed against a copper/copper alloy element which is melted to produce the molten copper/copper alloy. The infiltration of the graphite fiber structure with the molten copper/copper alloy is characterized by the absence of pressure on the molten copper/copper alloy.
