Abstract: A method of spreading fiber tows includes applying a coupling medium to a surface of a fibrous structure, positioning an ultrasonic probe adjacent to the surface of a fibrous structure, such that a tip of the ultrasonic probe is in contact with the coupling medium, moving at least one of the ultrasonic probe and the fabric structure relative to the other of the ultrasonic probe and the fibrous structure according to a first pattern, and imparting ultrasonic vibration with the ultrasonic probe to the surface of the fibrous structure while moving the ultrasonic probe along the surface of the fibrous structure. Imparting ultrasonic vibration to the surface of the fibrous structure spreads tows of the fibrous structure.

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 coated fiber structure for use in a ceramic matrix composite comprises a fiber and a fiber coating arrangement applied to and at least partially circumscribing the fiber. The fiber coating arrangement comprises a first boron nitride layer comprising exfoliated hexagonal boron nitride, a silicon carbide layer extending at least partially coaxially with and in direct contact with the first boron nitride layer, and a second boron nitride layer radially opposite the silicon carbide layer, with respect to the first boron nitride layer.

Abstract: A tooling fixture suitable for use in infiltrating a fibrous preform with a reactant gas includes an outer surface and opposing inner surface defining a thickness therebetween, and a plurality of holes extending through the thickness. Each hole of the plurality of holes includes an inlet at the outer surface, the inlet configured to receive a flow of the reactant gas, an outlet at the inner surface, a transition point between the inlet and the outlet, and an angled segment extending from the transition point to the outlet. Each hole of the plurality of holes has a first diameter at the inlet and a second diameter at the outlet, and the second diameter is greater than the first diameter.

Abstract: A ceramic matrix composite includes a fiber, a first interface coating layer disposed adjacent to an outer surface of the fiber, and a first protective layer disposed outward of the first interface coating layer and the fiber. The first protective layer comprises a high entropy ceramic. A method of protecting a fiber of a ceramic matrix composite includes depositing, by chemical vapor deposition or chemical vapor infiltration, a first interface coating layer on the fiber; and depositing, by chemical vapor deposition or chemical vapor infiltration, a first protective layer outward of the first interface coating layer. The first protective layer comprises a high entropy ceramic.

Abstract: A method of fabricating a tooling fixture suitable for use in infiltrating a fibrous preform includes generating a model of the tooling fixture, the model being conformal and complementary to a geometry of the fibrous preform, additively manufacturing the tooling fixture by extruding a carbon-containing ink in a layer-by-layer manner, and consolidating the extruded carbon-containing ink to form a consolidated tooling fixture.
