Abstract: A ceramic brush seal for a gas turbine engine, and a process for manufacturing the seal are provided. In one example, the process includes deinfiltrating an edge of a plurality of plies having a preimpregnated configuration. The edge is defined by a plurality of ceramic fibers extending away from a portion edge of a matrix infiltrated portion of each of the plies. In another example, the process includes masking an edge of a plurality of plies, the edge being defined by a plurality of ceramic fibers extending away from a portion edge of a body portion of each of the plies, and infiltrating the body portion of the plurality of plies with a ceramic matrix slurry. The plies are stacked, formed into a green body and then fired to form the component. The plies may include oxide/oxide woven ceramic fiber plies.

Abstract: In some examples, a method including applying a wet bond coat slurry to a damaged area of a coating system on a metal substrate, the bond coat slurry including a liquid binder, glass and/or glass-ceramic particles, and ceramic oxide particles; depositing fibers onto the wet bond coat slurry, wherein the fibers include metallic and/or ceramic fibers; applying a ceramic composite slurry on the bond coat while the bond coat is wet or at least partially dried to form a ceramic composite layer, the bond coat including a plurality of partially exposed fibers, wherein, following the application of the ceramic composite slurry, a first portion of fibers of the plurality of fibers are embedded in the bond coat and a second portion of fibers of the plurality of fibers extend into the layer of the ceramic composite slurry; and heating the bond coat and the ceramic composite layer to form a repaired portion of the coating system on the metal substrate, wherein heating the bond coat melts the glass particles and/or the gl
