ABSTRACT:
A method to produce high temperature oxidation resistant metal matrix composites by fiber diameter grading which comprises the steps of (a) laying up an alloy/fiber preform consisting of a plurality of alternating layers of metal alloy and fibers and (b) consolidating the preform under suitable conditions, wherein fibers of at least two diameters are employed and wherein the layers of fibers in the preform are graduated so that larger diameter fibers are located nearer what will become the exposed surface of the composite and smaller diameter fibers are located toward the interior of the composite.
