Abstract: A method for making large pressure vessels using a composite over-wrap process and a soluble mandrel structure that is scalable to a much larger vessel size than can normally be accommodated by the over-wrap process. The method allows the production of very large, lightweight vessels with no seams and no metal liners. Extensions of the method provide for the fabrication of fully embedded threaded or non-threaded bosses of composite materials, and fully embedded longitudinal and circumferential stringers or stiffeners.
