    Abstract: Methods for repairing composite component voids are provided. For example, one method comprises locating a void in a composite component and subjecting the composite component to a process for repair. The process for repair includes creating a flow path through the void, applying a filler material to the composite component at the flow path, and processing the composite component having the filler material. In some embodiments, the flow path has a first opening on a first side of the composite component and a second opening on a second, opposite side of the composite component. In other embodiments, at least one portion of the flow path extends at a first angle with respect to a lateral direction defined by the CMC component, and at least another portion extends at a second angle with respect to the lateral direction.

    Abstract: Systems and methods for thermally processing composite components are provided. In one exemplary aspect, a system includes a thermal system, a mover device, and a control system. The system also includes a plurality of vessels in which one or more components may be placed. The vessels are similarly shaped and configured. A vessel containing the one or more components therein may be mounted into a chamber defined by the thermal system during thermal processing. The thermal system and vessels include features that allow components to be thermally processed, e.g., compacted, burnt-out, and densified via a melt-infiltration process, a polymer impregnation and pyrolyzing process, or a chemical vapor infiltration process. utilizing the same thermal system and common vessel design. The control system may control the thermal system and mover device to automate thermal processing of the composite components.

    Abstract: Composite components and methods for adding a composite material to a composite component are provided. For example, a method comprises positioning a composite material segment against the composite component to form a component layup; applying an insulating material around at least a portion of the component layup to form an insulated layup; and densifying the insulated layup, where the composite component was previously densified before positioning the composite material segment against the composite component. In some embodiments, the composite material is ceramic matrix composite (CMC) and the composite material segment is a plurality of CMC plies. The composite component may be a CMC gas turbine engine component that comprises an original CMC component and a new CMC material segment joined to the original CMC component through the transfer of silicon between the original CMC component and the new CMC material segment during melt infiltration.
