Abstract

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