Abstract: A tooling assembly suitable for use in infiltrating a fibrous preform comprises an outer tooling fixture with a plurality of outer sidewalls defining an inner volume, each of the plurality of outer sidewalls having an outer wall thickness, and a window extending through the outer wall thickness of at least one outer sidewall of the plurality of sidewalls. The tooling assembly further comprises an inner tooling fixture positioned within the inner volume of the outer tooling fixture, the inner tooling having a plurality of inner sidewalls, each of the plurality of inner sidewalls having an inner wall thickness, and a plurality of holes extending through the inner wall thickness of at least one inner sidewall of the plurality of inner sidewalls. The at least one outer sidewall is positioned adjacent the at least one inner sidewall such that the window overlaps with at least a subset of the plurality of holes in the at least one inner sidewall.

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.

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.
