Abstract
A method is provided for fabricating metal matrix composites. Optical or reinforcing fibers, which may be in the form of monofilaments, mats, or tow, are consolidated into a metal matrix alloy. Grooves may be provided in the metal matrix material for holding and positioning the fibers. A transient liquid diffusion bonding agent in the form of a powder may be blended with powdered filler material, such as powdered matrix material, to provide a vehicle for consolidating the fibers into the metal matrix. The fibers and the blended powder are placed between layers of the metal matrix material and the whole structure is heated under minimal pressure to liquefy the bonding agent. The liquid bonding agent wets each fiber and interdiffuses with the matrix material, resulting in rapid isothermal solidification of the alloy and consolidation of the fibers in the matrix.
