Abstract:
Methods and features for repairing CMC components are provided. Methods include positioning a plurality of CMC plies at a damaged area of a CMC component and densifying the component and plies. For example, each ply may be a unidirectional ply positioned at the damaged area such that the plurality of plies is oriented in a plurality of directions. As another example, each ply may define a ply direction and comprise a plurality of ceramic fibers substantially extending along the ply direction, and the ply directions of at least two plies may be differently oriented. A repair patch for a CMC component also is provided that comprises a plurality of CMC plies. Fibers forming a first ply extend substantially along a first ply direction and fibers forming a second ply extend substantially along a second ply direction. The first and second plies of the repair patch are oriented in different directions.
