1. A method of repairing a core stiffened structure, the method comprising:
removing a damaged portion of the core stiffened structure; depositing a foam mixture into a cavity, the cavity being created by the step of removing the damaged portion of the core stiffened structure; allowing the foam mixture to expand and fill the cavity so as to form an expanded foam; trimming the expanded foam, wherein trimming the expanded foam comprises reducing an upper surface of the expanded foam until the upper surface of the expanded foam corresponds to a skin surface of the core stiffened structure; and placing a skin patch on the expanded foam.
