ABSTRACT:
The present invention comprises a process of forming a copper base alloy composite which is reinforced by graphite fibers, wherein the fibers are first coated with a continuous coating of an alloy constituent and then continuously coated with a coating of copper or a copper base alloy. The coated fibers are then heated in a vacuum under applied load, in combination with copper or a copper base alloy at a temperature above the melting point of the copper or copper base alloy but below the melting point of the alloy to be formed from the copper or copper base alloy and the alloy constituent with which said graphite fiber has first been coated.
