Patent number: 6468928Abstract: A translucent sheet is made of a textile net middle layer that is between two cover layers made of translucent films. In the middle layer, areas of the mesh run at an angle to the main direction of stress. In addition, there are stabilizing threads that run in the main direction of stress and are bonded to the knots of the textile net middle layer and give the structure of the middle layer particular strength in the main direction of stress.Type: GrantFiled: May 11, 1999Date of Patent: October 22, 2002Assignee: Benecke-Kaliko AGInventors: Konrad Eysel, Lothar Bargiel, Walter Rother, Günther Vogt

Patent number: 6468613Abstract: Light metal/CFRP-made structural members which are characterized in that they are structural materials in which a CFRP material is stuck to the surface of a light metal material via an adhesive agent layer of thickness at least 10 &mgr;m and up to 500 &mgr;m, and the volume resistivity of the adhesive agent layer between said metal material and said CFRP material is at least 1×1013 &OHgr;.cm and, furthermore, the adhesive strength at room temperature is at least 15 MPa. In accordance with the present invention, since conventional light metal/CFRP structural materials can be made lighter and, furthermore, since the resistance to galvanic corrosion is outstanding and it is possible to markedly enhance the strength and the impact energy absorption performance, the development of applications and large-scale expansion into new fields becomes possible. Weight reduction and enhancing the durability and reliability of structures also makes a considerable contribution in terms of environmental protection.Type: GrantFiled: April 20, 1999Date of Patent: October 22, 2002Assignee: Toray Industries, Inc.Inventors: Akihiko Kitano, Kenichi Yoshioka, Kenichi Noguchi, Hitoshi Nishiyama

Patent number: 6468654Abstract: A treating agent comprises a nitrile group-containing highly saturated polymer rubber latex (A) having an iodine value of 120 or less, a rubber latex (B) other than the highly saturated polymer rubber latex, and a water-soluble resorcinol/formaldehyde condensate in amounts of 15 to 80%, 5 to 70% and 2 to 15%, all by weight in terms of solids, respectively. A rubber-reinforcing fiber product is coated with the treating agent. A rubber article such as a toothed belt, a tire and the like is made using this rubber-reinforcing fiber product. The glass fiber product coated with the treating agent may be further coated with a halogen-containing polymer-based adhesive as a secondary treating agent. Thus, the treating agent exhibits a large bonding force between the reinforcing fiber product and a matrix. Even if the rubber article is repeatedly subjected to a flexing stress, the strength thereof cannot be reduced. A peel-off cannot occurs between the reinforcing fiber product and the rubber matrix.Type: GrantFiled: August 13, 1998Date of Patent: October 22, 2002Assignee: Nippon Glass Fiber Co., Ltd.Inventors: Akira Okamura, Masato Sekiguchi

Patent number: 6465100Abstract: A method to form a sealed, partially or fully densified fiber reinforced composite preform which comprises: impregnating said preform with a major portion of a liquid, ceramic-forming precursor; initiating cure of the outer surface of said precursor with radiation, such as actinic radiation; a thereby forming a sealing barrier or skin on the surface of said preform. In a second embodiment the preform is infiltrated with a thermoplastic as liquid, frozen, excess frozen infiltrate optionally removed from the preform surface, then the preform is coated with a liquid which is curable with radiation, cure is initiated with radiation and the preform is sealed with a barrier coat.Type: GrantFiled: June 15, 1993Date of Patent: October 15, 2002Assignee: Alliant Techsystems Inc.Inventors: William L.

Patent number: 6444756Abstract: Novel polymer compositions for controlling or correcting dispersion mismatch between the composition and a side-fiber polished optical fiber are disclosed. The polymer compositions contain an infrared absorbing dye having an absorption maximum from about 900 to about 1200 nm and and a polar olefin copolymer containing monomers which are formed from polar olefins having an ester, benzene, or halogen substitutent attached. A method for controlling the dispersion exhibited by the novel polymer compositions is also disclosed. The method includes forming the polymer composition over an exposed surface of an optical fiber. Dispersion is controlled by controlling the amount of dye present in the polymer composition. Also disclosed is an optical device from which improvements in the uniformity of spectral response and performance are observed across a wavelength band. The optical device includes the polymer composition formed over an optical fiber.Type: GrantFiled: June 29, 2001Date of Patent: September 3, 2002Assignee: Molecular OptoElectronics CorporationInventors: Kwok Pong Chan, David G. Gascoyne, Gregory A. Wagoner

Publication number: 20020090490Abstract: A laminated product according to the present invention has a fiber reinforced resin layer, an elastic layer laminated on one surface of the fiber reinforced resin layer, and a surface protection layer laminated on a surface of the elastic layer for protecting the surface of the elastic layer. The fiber reinforced resin layer includes at least two prepreg sheets, each of which is formed by impregnating a thermoplastic resin into continuous reinforcing fibers arrayed in one direction such that the volume ratio of the continuous reinforcing fibers is in the range of 40 to 80%. The prepreg sheets are laminated so as to the array directions of the continuous reinforcing fibers at right angles.Type: ApplicationFiled: December 21, 2001Publication date: July 11, 2002Inventors: Tamio Kawasumi, Kazuaki Kouda

Publication number: 20020076522Abstract: Apparatus and methods are presented for reinforcing and stiffening a printed circuit board (PCB) in selected locations by utilizing preferentially oriented fibers. Selected fibers within the polymeric material matrix of the PCB fiber-matrix layer are removed and replaced with a similar quantity of fibers in a preferential orientation. Various combinations of layering of modified fiber-matrix layer material with conventional fiber-matrix layer material are presented to achieve the desired PCB stiffening. Printed circuit boards, under the weight of heavy attached electronic components, may deflect or flex along an axis, defined as the characteristic fold. This flexing is exasperated with manufacturing and handling loading, particularly when mounted in a chassis. Preferentially orientated fibers laid transverse to the characteristic fold reinforces the area to resist flexure within the area surrounding the characteristic fold.Type: ApplicationFiled: December 14, 2000Publication date: June 20, 2002Applicant: Intel CorporationInventors: George Hsieh, Terrance J.

Patent number: 6405763Abstract: The weft threads (14) of a textile product (10) run at an angle of at least approximately 70 degrees with respect to its warp threads (12) and the weft threads (14) protrude, by a piece, beyond the outermost warp threads (12′), on at least one side of the strip-shaped textile product (10) in a strip-shaped textile product (10), consisting, in particular, of filaments, threads, or a yarn, for use as a reinforcement layer for hoses, tubes, pressure containers, and similar hollow objects. Alternately or in addition, the warp threads (12) are formed thinner than the remaining warp threads (12) in at least one boundary area (R) of the textile product (10).Type: GrantFiled: January 4, 2002Date of Patent: June 18, 2002Assignee: Milliken & CompanyInventors: Willy De Meyer, Michael Gilpatrick

Publication number: 20020071932Abstract: An article and method for reinforcing structural members is provided. The article comprises a carbon fiber material, preferably a carbon fiber mesh with a roughened surface defined by an epoxy resin. The article has lateral fibers woven into longitudinal carbon fibers that are in tension, creating a mesh. An epoxy resin is applied to the fiber mesh to form a rigidified fiber mesh tape once the resin is cured. To obtain a roughened surface a plastic sheet is removably attached to the surface of the fiber mesh. The plastic sheet is removed thereby exposing a roughened carbon fiber surface defined by the epoxy. The rigidified fiber mesh tape is adhered to the structural member by applying a second epoxy to the structural member. The roughened surface of the rigidified carbon fiber mesh material is then joined to the second epoxy resin. To firmly adhere the fiber mesh to the structural member an impermeable material and a plastic barrier are placed above the article and the structural member.Type: ApplicationFiled: July 11, 2001Publication date: June 13, 2002Inventors: Donald G.
