ABSTRACT:
Method for making a composite containment casing having an integrated abradable system involving providing a mandrel having a pocket, positioning a sandwich structure into the pocket, applying at least one ply of a material about the mandrel having the pocket containing the sandwich structure therein to produce a containment casing preform, infusing a resin into the containment casing preform, curing the containment casing preform to produce a containment casing, and applying at least one abradable layer to the sandwich structure of the containment casing to produce the containment casing having the integrated abradable system.
