Patent number: 11839997Abstract: A method of fabricating a composite structure includes laying at least one composite ply about a bladder, the bladder comprising a phase change material in a first phase having a first volume, positioning an outer mold about the bladder and the at least one composite ply, and curing the at least one composite ply to form the composite structure. Curing causes the phase change material contained within the bladder to change to a second phase to expand from the first volume to a second volume and apply a pressure to an interior surface of the composite ply and press an outer surface of the composite ply against the outer mold to form an interior cavity. The bladder is not removable from the formed interior cavity.Type: GrantFiled: March 24, 2023Date of Patent: December 12, 2023Assignee: SIKORSKY AIRCRAFT CORPORATIONInventor: Jonathan K. Garhart
