Containment case and method of manufacture

A containment case comprising:

• a composite core with an inner surface and an outer surface;
• at least one puncture resistant layer disposed in a primary impact zone and integrated with the composite core, wherein the at least one puncture resistant layer is configured coextensive with a length of the composite core and includes a resin to bond the at least one puncture resistant layer to the inner surface of the composite core, the at least one puncture resistant layer characterized by a high through-thickness shear strength and a high interlaminar toughness at impact;
• and
• at least one energy capture layer disposed in a primary impact zone and integrated with the composite core, wherein the at least one energy capture layer is configured coextensive with a length of the composite core and includes a resin to bond the at least one energy capture layer to the outer surface of the composite core, the at least one energy capture layer characterized by a high in-plane tensile strength and low resistance to delamination and fiber-matrix debonding at impact.

A method of fabricating a containment case, the method comprising:

• disposing one or more layers of a puncture resistant material on a layup mandrel;
• disposing one more layers of a structural composite material on an exterior surface of the puncture resistant material;
• disposing one or more layers of an energy capture material on an exterior surface of the structural material;
• and
• curing a resin in the composite core, the one or more layers of the puncture resistant material and the one or more layers of the energy capture material.
