Patent number: 7867589Abstract: A lightweight, high-pressure cryogenic tank construction includes an inner layer comprising a matrix of fiber and resin suitable for cryogenic use. An outer layer in intimate contact with the inner layer provides support of the inner layer, and is made of resin composite. The tank is made by placing a fiber preform on a mandrel and infusing the preform with the resin. The infused preform is then encapsulated within the outer layer.Type: GrantFiled: July 20, 2007Date of Patent: January 11, 2011Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Thomas K.
