Abstract: A ceramic composite tubular structure includes a monolithic ceramic preform being tubular-shaped created using an additive manufacturing process. The monolithic ceramic preform includes a first end, a second end, an inner surface, and an outer surface. The monolithic ceramic preform includes one or more apertures formed between the inner surface and the outer surface where at least one of the one or more apertures is open to at least one of the first end or the second end. An inner face sheet is formed on the inner surface of the monolithic ceramic preform by a first quantity of ceramic matrix composite plies. An outer face sheet is formed on the outer surface of the monolithic ceramic preform by a second quantity of ceramic matrix composite plies.

Abstract: A method of producing a ceramic matrix composite component. The method includes positioning a first plurality of ceramic matrix composite plies on top of one another, disposing a filler pack on the first plurality of ceramic matrix composite plies, and positioning a second plurality of ceramic matrix composite plies on top of the filler pack. One of the first plurality of ceramic composite plies or the second plurality of ceramic composite plies includes a bend angle, to define an interstice between the plurality of ceramic matrix composite plies with the filler pack disposed in the interstice. The filler pack includes one or more sacrificial fibers disposed therein, that subsequent to removal provide a functional feature, such as a cooling manifold in the filler pack. The method further includes forming one or more channels coupled to the one or more functional features for the flow of a cooling fluid therethrough. A ceramic matrix composite is also disclosed.

Abstract: A ceramic matrix composite (CMC) component and method of fabrication including one or more elongate functional features formed in multiple fiber plies of the CMC component. The CMC component includes a plurality of longitudinally extending ceramic matrix composite plies in a stacked configuration. Each of the one or more elongate functional features includes an inlet and an outlet to provide a flow of fluid from a fluid source to an exterior of the ceramic matrix composite component. The one or more elongate functional features are configured in multiple plies of the plurality of longitudinally extending ceramic matrix composite plies to form a plurality of cooling channels in multiple plies of the ceramic matrix composite component.
