Abstract: A method includes forming a ceramic matrix composite component by infiltrating an array of ceramic-based fibers with a ceramic-based matrix; forming a plurality of cooling holes in the ceramic matrix composite component; applying a slurry of particles in a carrier fluid to the ceramic matrix composite component such that the slurry passes through the cooling holes and wicks into the ceramic matrix composite material; and processing the ceramic matrix composite component to remove the carrier fluid, thereby leaving a filler at a wall surface of the plurality of cooling holes. A component is also disclosed.

Abstract: A method of producing an enhanced ceramic matrix composite includes applying a tackifier compound to a fiber preform. The tackifier compound includes inorganic filler particles. The method further includes modifying the tackifier compound such that the inorganic filler particles remain interspersed throughout the fiber preform, and occupy pores of fiber preform.
