Abstract

A process for fabricating a melt-infiltrated ceramic matrix composite comprising fabricating a ceramic fiber preform comprising a fiber, a fiber tow, or both; depositing a structural support material coating on the fiber, the fiber tow, or both to form a partially densified ceramic matrix composite comprising at least one pore, at least one porous network or both; depositing a fiber protection material coating on the fiber, the fiber tow, or both; infiltrating a slurry composition comprising a solvent into the pore, the porous network or both; drying the partially densified ceramic matrix composite to remove the solvent; depositing a sacrificial material coating on the fiber protection material coating; and, melt-infiltrating a molten infiltrant into the partially densified ceramic matrix composite to form a melt-infiltrated ceramic matrix composite.
