Publication number: 20090142557Abstract: A material and method for production of ballistic armor. One or more absorbing layers are inserted between layers of woven cloth made of high strength fibers. Mechanical energy absorbing layers are of two types, either a large number of small objects in loose contact with one another which will dissipate energy by moving traversely to the direction of impact, embedded in a matrix along with randomly oriented high strength fibers, or a large number of small objects in a matrix along with parallel oriented high strength fibers. A method for production of such a layered device is also taught. The material may be used in body armor including vests and helmets as well as applied to construction of shields and armored vehicles.Type: ApplicationFiled: November 22, 2004Publication date: June 4, 2009Inventor: Montgomery G.B.

Patent number: 7527848Abstract: A laminate material for hook-and-loop closures, comprising a carrier film and a textile substrate laminated onto the carrier film. The textile substrate has loops on its surface that are suitable for connecting with hook-and-loop hooks, wherein the carrier film and the textile substrate are not connected over their entire area. A method for producing a laminate material for hook-and-loop closures comprises applying an adhesive to a carrier film in a pattern that is composed of adhesive areas and adhesive-free regions, applying a material web of a textile substrate to the side of the carrier film provided with adhesive to form a two-ply web, the textile substrate having loops on its surface that are suitable for connecting with hook-and-loop hooks; and passing the two-ply web through a roller nip of a pair of rollers, which presses the carrier film and the textile substrate together.Type: GrantFiled: October 7, 2004Date of Patent: May 5, 2009Assignee: Nordenia Deutschland Gronau GmbHInventor: Georg Baldauf

Patent number: 7510758Abstract: A breathable, elastic, film laminate including layers of an inherently breathable, elastic polymer film alternately stacked with layers of a filled plastic polymer. The laminate may be made by grafting a thermoplastic polymer to an elastomer to form an inherently breathable elastic polymer, extruding, the elastic polymer through a die, extruding the filled plastic polymer through a die, stacking the extruded elastic polymer with the extruded plastic polymer while the polymers are in a melt-extrudable state to create a multilayer film laminate, and stretching the laminate.Type: GrantFiled: November 12, 2002Date of Patent: March 31, 2009Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Oomman Painumoottil Thomas, Vasily Aramovich Topolkaraev, Stephen Clark Smith, Susan Elaine Shawver

Publication number: 20090041985Abstract: The invention relates to a method for producing a composite component reinforced by stiffening elements. Composite component is produced by the inside gluing of a monolithic component to a multiplicity of stiffening elements by means of an adhesive suitable for this particular application. Stiffening elements are formed with a fibre reinforced, amorphous thermoplastic material. Monolithic component of composite component consists of a fibre reinforced duroplastic material—for example a composite epoxy matrix—in which are embedded, for reinforcement, carbon fibres, basalt fibres, natural fibres, ceramic fibres, aramide® fibres, kevlar® fibres or any combination thereof. Monolithic component is glued to thermoplastic stiffening elements by an adhesive under the influence of pressure and temperature. Here a tolerance compensation is carried out essentially by stiffening elements, if necessary being plastically deformed, so that high dimensional stability is achieved.Type: ApplicationFiled: July 17, 2008Publication date: February 12, 2009Inventors: Klaus Von Varendorff, Martin Staub, Arne Mashoff

Publication number: 20090029122Abstract: The invention relates to a process for the bonding of a fibre-reinforced material to an injection-moulding material. The invention further relates to an article produced according to the process. It is an object of the invention to improve the bond between a fibre-reinforced starting material and a material applied by injection. To achieve the object, a fibre-reinforced plastics material is heated locally, and further plastics material is applied by injection. This produces a particularly good coherent bond between the further plastics material and the fibre-reinforced plastics material. Ease of handling is also provided. The invention relates to a component produced according to the process and also to an apparatus for carrying out the process.Type: ApplicationFiled: February 19, 2007Publication date: January 29, 2009Applicant: LANXESS DEUTSCHLAND GMBHInventor: Frank Krause
