Abstract

Fiber-reinforced ceramic matrix composite articles are fabricated by combining inorganic reinforcing fibers with dispersions of powdered ceramic matrix materials in organic vehicles which are thermoplastic solids. The dispersions are solid at room temperature, and are melted and combined with the fibers as heated liquid dispersions. Following application to the fibers, the thermoplastic dispersions are solidified by simple cooling; no solvent removal or drying step is required.
