Patent number: 6479148Abstract: A rocket motor assembly is insulated or thermally protected with a rocket motor ablative material formed from a prepreg. The prepreg contains at least an impregnating resin matrix and, as a precursor prior to carbonization, either carded and yarn-spun solvent-spun staple cellulosic fibers, solvent-spun cellulosic filaments, or a combination thereof. When patterned and carbonized, the rocket motor ablative material can be lined or otherwise placed into a rocket motor assembly, such as between the solid propellant and case, in the bulk area of the exit nozzle liner, or at susceptible portions of a re-entry vehicle, such as the nose cone.Type: GrantFiled: August 19, 1999Date of Patent: November 12, 2002Assignee: Cordant Technologies Inc.Inventors: Kenneth P. Wilson, John K. Shigley, Allan P. Thompson

Patent number: 6391446Abstract: Textile elements made of fibres which contain from 40% to 99.9% silicon dioxide and are coated with a silicone-containing emulsion are disclosed. The emulsion includes an anionically stabilized hydroxylated polydiorganosiloxane contains two hydroxyl groups which are linked with silicone by molecule and colloidal silica. The textile elements demonstrate considerable wear resistance. Methods of preparing the same are also disclosed.Type: GrantFiled: December 9, 1999Date of Patent: May 21, 2002Assignee: RELATS, S.A.Inventor: Pere Relats Casas

Patent number: 6358591Abstract: An insulation blanket is disclosed that contains fire-blocking materials for preventing rapid penetration of fire into an aircraft fuselage in case of a fire outside the aircraft. The insulation blanket contains at least one layer of fiberglass or other thermal-acoustic insulation material without fire-blocking properties, and one or more layers of fire-blocking material. The fire blocking material is wider than the thermal-acoustic insulation so that it may be folded against and attached to adjacent structural frame members of the fuselage. In the alternative, a thermal-acoustic insulation material is used that has fire-blocking properties instead of the separate layers of fire-blocking and thermal-acoustic insulation materials. A method for installing insulation blankets according to the present invention is disclosed, whereby a fire-blocking insulation portion of the blanket is folded against and attached to frame members of the aircraft using attachment posts or spring clips.Type: GrantFiled: June 4, 1999Date of Patent: March 19, 2002Assignee: Orcon CorporationInventor: Sherman S.
