Abstract

A process for fabricating a melt-infiltrated ceramic matrix composite, comprising the steps of fabricating a ceramic fiber preform comprising fibers, fiber tows, or both fibers and fiber tows (20, 30); depositing a structural support material on the fibers, the fiber tows, or the fibers and fiber tows to form a partially densified ceramic matrix composite comprising pores, a porous network or both pores and a porous network; preparing a slurry composition comprising sacrificial particles (10); infiltrating the slurry composition into the partially densified ceramic matrix composite and depositing the sacrificial particles into the pores, the porous network or both the pores and porous network; freeze-drying a slurry infiltrated partially densified ceramic matrix composite; sublimating a frozen slurry infiltrated partially densified ceramic matrix composite; and, melt-infiltrating a sublimated partially densified ceramic matrix composite to form a melt-infiltrated ceramic matrix composite.
