Zusammenfassung:	Methods for repairing composite containment casings involving providing a composite containment casing having an integrated abradable system (35), the abradable system (35) having at least one damaged portion, and including a sandwich structure (36), and at least one abradable layer (38), removing the damaged portion of the abradable system to leave a hole, shaping a sandwich structure segment to produce a shaped sandwich structure, placing the shaped sandwich structure into the hole in the abradable system, infusing a resin into the shaped sandwich structure, and curing the containment casing having the shaped sandwich structure, and applying at least one abradable layer to the shaped sandwich structure to produce the containment casing having a repaired integrated abradable system.
