A method of producing a ceramic matrix composite comprising: a) applying a fiber interface coating to the composite, b) coating the composite via chemical vapor infiltration, and c) infiltrating the composite with molten material, wherein the composite is not removed from a tool between steps (a), (b), and (c), wherein the fiber interface coating and the chemical vapor infiltration are forced flow processes, wherein the forced flow fiber interface coating applies a pressure gradient of about 0.005 to about 1.0 atm, wherein the coating is carbon, boron nitride, or silicon doped boron nitride, wherein the chemical vapor infiltration applies silicon carbide, silicon nitride carbide, boron carbide, or carbon as a coating, wherein the coating is about 0.1 [micro]m to about 15.0 [micro]m, wherein the ceramic matrix composite is a tool, wherein the molten material comprises an alloy, wherein the molten material comprises silicon carbide, carbon, or a ceramic particulate, wherein the composite is multi-layered, wherein at least one layer comprises at least one of a carbide, a nitride, a boride, or carbon, for instance one layer is silicon carbide or boron nitride. |
