Publication number: 20110265235Abstract: The general field of the invention is that of helmet shells made of composite material comprising at least one “armure” of fabrics impregnated with a resin matrix. Certain parts of the “armure” are impregnated with a resin matrix comprising an additive adapted to reinforce the mechanical strength of the helmet, the said parts corresponding to the weakest zones of a human head, such as the top of the head or the ears. Preferably, the resin is of the epoxy type and the additive is based on acrylic block copolymers. More precisely, the additive is of the “Nanostrength®” brand.Type: ApplicationFiled: November 2, 2010Publication date: November 3, 2011Applicant: THALESInventors: Jean-Noël Perbet, Christophe Coupeaud, Laurent Laluque, Joël Baudou, Philippe Viot, Sébastien Denneulin, Virginie Rejsek, Matthieu Gervais, Alain Soum

Patent number: 8047238Abstract: A liner for repairing damaged pipes, such as underground sewer or gas pipes is disclosed. The liner comprises a TPU coating on a fibrous mat of non-woven fabric. The TPU coating is a high heat resistance polyester TPU which allows an epoxy resin/amine to be saturated in the non-woven fabric and the cure initiated by the use of steam or hot water. The cured epoxy resin converts the liner from a flexible state to a rigid state as the liner is cured in place inside the pipe. The TPU containing liner may also be used with thermoset resins other than epoxy resins, such as polyester resins and vinyl ester resins.Type: GrantFiled: January 17, 2008Date of Patent: November 1, 2011Assignee: Lubrizol Advanced Materials, Inc.Inventors: Robert J. Wiessner, Donald A. Meltzer

Patent number: 8043674Abstract: Heat-sealable, multi-layer composite packaging structures that are suitable for packaging and having improved sealing properties and simplified construction as compared to prior art composite film constructions are disclosed. The inventive film structure includes a first substrate, such as paper, bonded such as by extrusion lamination, to a sealable, high-barrier film. This inventive “paper-adhesive-polymer” lamination may replace prior art “paper-adhesive-foil-adhesive” foil-based tandem laminations. An improved or comparable polymer film substrate may replace the “foil-adhesive” layer components of the popular incumbent prior art structure.Type: GrantFiled: September 15, 2006Date of Patent: October 25, 2011Assignee: ExxonMobil Oil CorporationInventors: Richard Alan Rehkugler, Salvatorf J. Pellingra, George F. Cretekos, Benoit Ambroise

Patent number: 8043678Abstract: The present invention relates to a radome which has excellent transmission loss of radio waves and structural strength, which can be easily produced, and which has favorable workability, and a method of producing the same. The radome includes an olefin woven material and a glass cloth, in which the olefin woven material and the glass cloth are impregnated with a matrix resin to be integrated with each other, and the glass cloth is disposed closer to an inner side of the radome than the olefin woven material. As the olefin woven material, a woven material formed of an ultrahigh molecular weight polyethylene fiber can be used. As the matrix resin, an epoxy resin, a vinyl ester resin, an unsaturated polyester resin, or a silicone resin can be used.Type: GrantFiled: October 29, 2008Date of Patent: October 25, 2011Assignee: Mitsubishi Electric CorporationInventors: Shigeru Utsumi, Muneo Murakami, Kimihiro Kaneko, Teruhiko Kumada

Patent number: 8039069Abstract: A composite part including a fibrous assembly including at least two preforms each of which includes layers of fibrous cloths. Each preform includes at least one opening or protruding structure which is substantially complementary to the structure of the other preform. The first and second preforms are engagement with one another and are firmly connected by a polymer matrix being injected around the preforms.Type: GrantFiled: June 13, 2007Date of Patent: October 18, 2011Assignee: SKF Aerospace FranceInventors: Jean-Michel Buchin, Michel Genot

Publication number: 20110236614Abstract: A net-shaped protective material for wire harness sheathing which has flame retardancy and is free from mesh deformation. Vertical strands (2) and horizontal strands (3) which are constituted of a flame-retardant resin wire having an elliptic sectional shape have been pressed and hot melt bonded at the intersections (4) thereof to form a net shape. The vertical strands and horizontal strands are superposed at the intersections without interlacing, and one or both of the vertical strands and horizontal strands are melted in a state where 40% to 50% of the sectional area has been melted and embedded in the other strands. The protective metal has a cut end which has undergone fraying prevention processing.Type: ApplicationFiled: November 18, 2009Publication date: September 29, 2011Applicant: SUMITOMO WIRING SYSTEMS, LTD.Inventors: Tadao Ushikai, Tetsuya Iwasaki

Publication number: 20110232002Abstract: A TPU composition comprising two or more TPU polymers is disclosed. The TPU composition gives a broad process window for melt coating applications. The blend of TPUs give better processing than either of the individual TPU polymers used in the blend alone. This results in melt coating which gives less matt and glossy streaks and allows faster coating speeds along with lower coating weight. The two or more TPU polymers used in the blend have a different soft segment. The different soft segment is created by using different molecular weight polyol for the TPU polymers or by using chemically different polyols.Type: ApplicationFiled: September 2, 2009Publication date: September 29, 2011Applicant: LUBRIZOL ADVANCED MATERIALS, INC.Inventor: Robert J.

Patent number: RE43867Abstract: 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, carded and spun staple cellulosic fibers. 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: May 22, 2003Date of Patent: December 18, 2012Assignee: Alliant Techsystems Inc.Inventors: Kenneth P. Wilson, Shelley Rawding, legal representative, John K. Shigley, Allan P. Thompson
