ABSTRACT:
The method provides a process for fabricating metal matrix composites. First the process coats the fibers with nickel by electrodeposition or gaseous deposition to form nickel-coated fibers. Over-plating the nickel-coated fibers with aluminum by either electrodeposition in a non-aqueous electrolyte or gaseous deposition forms aluminum-coated-nickel-coated fibers. Sintering this product under compression, perpendicular to the fiber's central axis, forms the final metal matrix composite. The metal matrix composite has a nickel-aluminum matrix, very few voids and extended unbroken lengths of fibers within the nickel-aluminum matrix.
