Rapid ceramic matrix composite production method

摘要

A method of producing a ceramic matrix composite component for use in a gas turbine engine comprising forming a ceramic matrix composite component, assembling the preform in a tool, loading the tool into a furnace and infiltrating the preform. Infiltrating the preform may include the methods of CVI, CVD, slurry infiltration, and melt infiltration.

1. A method of producing a ceramic matrix composite comprising a) applying a fiber interface coating to fibers b) coating the fibers via chemical vapor infiltration to create a coated fiber composite, and c) infiltrating the coated fiber composite with a molten material via melt infiltration, wherein the fibers are not removed from a tool in a furnace between steps (a), (b), and (c), and wherein the tool comprises a tool inlet port configured to accommodate the intake of gas and of molten material, and a tool exhaust port, wherein the tool exhaust port includes an outlet with a material in the outlet, the material permitting gas flow therethrough and creating a seal by blocking particulate and/or reacting with the molten material.
