Abstract: A coated fiber structure for use in a ceramic matrix composite comprises a fiber and an interface coating arrangement applied to and circumscribing the fiber. The interface coating arrangement comprises a first boron nitride layer, a silicon carbide layer extending coaxially with and in direct contact with the first boron nitride layer, and a second boron nitride layer on a side of the silicon carbide layer opposite the first boron nitride layer. The thickness of the silicon carbide layer ranges from 100 nm to 500 nm, and an RMS roughness of the silicon carbide layer is less than 20 nm.

Abstract: A fixture for processing a ceramic matrix composite article includes first and second tool segments that each have an exterior side and an interior side. The tool segments define there between a working region for holding a fiber preform that is to be densified with a ceramic material. Each of the interior sides has grooves there along for delivering a precursor gas to the working region.

Abstract: A tooling assembly suitable for use in chemical vapor infiltration (CVI) comprises a plurality of tooling fixtures arranged as a tower, with a central channel extending therethrough along a channel axis, and a lid atop the tower and covering the central channel. Each tooling fixture of the plurality of tooling fixtures comprises a plurality of walls defining an internal volume, and a plurality of holes through at least one wall of the plurality of walls, the plurality of holes placing the internal volume in flow communication with an external environment. Each tooling fixture of the plurality of tooling fixtures is in physical contact with an adjacent tooling fixture.

Abstract: A chemical vapor deposition system comprises a reactor including at least one wall extending between an inlet end and an outlet end, and an internal volume defined by the at least one wall, the inlet end, and the outlet end. The reactor further comprises a heat source in thermal communication with the internal volume, and a solid precursor container removably placed within the internal volume. The solid precursor container includes at least one internal cavity for holding an amount of the solid precursor, and an opening fluidly connecting the at least one internal cavity to the internal volume of the reactor. The solid precursor comprises at least one of aluminum, zirconium, hafnium, and a rare earth metallic element.
