Abstract

Reinforced metallic or intermetallic alloy matrix composite materials which are reinforced by the incorporation of preferably small-diameter ceramic fibers infiltrated within a metal bonding layer. The bonding layer comprises a foil, such as copper, which forms a molten eutectic alloy with the major metal of the matrix alloy, such as titanium, and infiltrates the fibers to form a unitary reinforced composite.
