Abstract
A porous fiber preform enclosed within a mold may be melt infiltrated by pouring a molten material through an inlet of the mold, the porous fiber preform comprising ceramic fibers. A ceramic matrix composite component comprising the ceramic fibers may be formed by solidifying the molten material that is in the mold and in the porous fiber preform.
Claims20
A method of forming a ceramic matrix composite component, the method comprising:
- positioning a porous fiber preform, which comprises a plurality of ceramic fibers, into a cavity defined by an inner surface of a mold, the mold including an inlet into the cavity;
- melt infiltrating the porous fiber preform by pouring a molten material through the inlet of the mold into the cavity;
- and
- solidifying the molten material, wherein the inner surface of the mold corresponding to an outer surface of the ceramic matrix composite component after the molten material is solidified.
