• providing a mandrel having a pocket;
• positioning a sandwich structure into a first portion of the pocket;
• applying at least one ply of a material about the mandrel in at least the pocket;
• applying a strip about the material in a second portion of the pocket to produce an integrated fragment catcher preform;
• applying at least one ply of the material about the mandrel having the sandwich structure and the integrated fragment catcher preform to produce a containment casing preform;
• infusing a resin into the containment casing preform;
• curing the containment casing preform;
• and
• applying at least one abradable layer to the sandwich structure to produce the containment casing having the integrated fragment catcher and the integrated abradable system.
