Abstract: The present disclosure is directed to a method for forming a passage in a composite component. The method includes forming a cavity in a fiber preform. The cavity forms a portion of the passage. The method also includes inserting a core into the cavity and placing one or more fiber plies onto the fiber preform to form a fiber preform assembly. The method further includes thermally processing the fiber preform assembly and densifying the fiber preform assembly to form the composite component. The method also includes removing the core from the composite component.

Abstract: A method for treating a field operated component is disclosed which includes providing the component including a ceramic matrix composite and removing a first portion of the component, forming a first exposed surface on the component. The method further includes providing a second portion including the composite, the second portion having a second exposed surface including a conformation adapted to mate with the first exposed surface. The second portion is positioned in association with the component so as to replace the first portion, and the second portion and the component are joined to form a treated component. Another method is disclosed wherein the component is a turbine component which further includes removing an environmental barrier coating from the component, arranging and conforming the first exposed surface and the second exposed surface to define a joint, and applying an environmental barrier coating to the treated component.

Abstract: Frame assemblies, molds, and methods for forming rotor blades are provided. A frame assembly for a rotor blade mold includes a plurality of frames, at least one of the plurality of frames movable relative to the others of the plurality of frames, and a bed supported by the plurality of frames. Movement of the at least one of the plurality of frames causes a modification of the bed along a width-wise axis. A mold for forming a rotor blade includes a frame assembly and a mold material disposed in the bed of the frame assembly.
