Woven Or Felted Sheet-form Work Patents (Class 264/324)
  • Patent number: 8992813
    Abstract: A component made of at least one thermoformable material, having a first layer made of a first material, a second layer made of a second material, and a third layer made of the first material. The three layers form a sheet, which is formed to various shapes, depending upon the part that is to be created. The sheet may be formed to produce the bumper of an automobile, a door panel for an automobile, a flotation device, such as a pontoon for a pontoon boat, or the like. The first and third layers are SMC, and the second layer, or “core,” is disposed between the first and third layers, allowing the strength of the first and third layers to be used more efficiently, compared to a sheet having only the first and third layers, and no core.

  • Patent number: 8858857
    Abstract: A method of fabricating a composite vessel encompassing rapid manufacturing that is applicable to composite hydrogen and other gas storage tanks, both for high-pressure cylinders, as well as low-pressure conformal tanks. The process of fabrication includes using a liner, of metal or plastic materials, over which a braided or developed preform is wrapped. The dry fiber wrapped liner is placed in a mold and resin injected into the cavity formed between the liner and the mold outer walls. The liner is flooded with heated and/or cooled pressurized fluid thus enabling complete and independent process control from within the liner for both the resin injection and the cure phases. Fiber placement control is determined through combined biaxial and triaxial braid/preform design, and by wrapping at controlled tension onto the supporting liner. Fiber tension control is further enhanced by the methodology of mold loading whereby tensioning forces are enacted during actual load and close.

  • Publication number: 20140263033
    Abstract: A process is disclosed for forming a three-dimensional structure from a nonwoven web. The web is made of synthetic polymer filaments. The process comprises subjecting the web to a molding force at a temperature between the glass transition temperature and the melting temperature of the polymer. The nonwoven web is constructed so as to allow ample elongation of the constituent filaments. The web is preferentially bonded in selected areas. The filaments are only partially drawn during the spinning process, so as to preserve elongation potential. The three-dimensional structures made by the process can be shaped filters, for example for use in beverage capsules.

    Abstract: The present invention is a composite laminated sheet material suitable for structures such as containment sumps. The laminated material comprises a fabric-backed thermoplastic layer upon which thermoset plastic is applied to the fabric side. The thermoplastic layer is formed by contacting a layer of fabric onto a layer of molten thermoplastic such that the liquid thermoplastic permeates a portion of the fabric layer to form a mechanical bond with the fabric layer when the thermoplastic layer cools and hardens. Thermoset plastic, such as fibreglass resin, is sprayed onto the fabric side of the thermoplastic layer to allow the liquid resin to permeate the fabric layer. Once the resin cures and hardens, the fabric layer is mechanically bonded to the cured thermoset plastic layer to effectively bond the thermoplastic layer to the thermoset plastic layer.

The method can include heating the stitched plies to soften or melt the fusible thread. The use of fusible thread can act as an in situ binder within the non-crimp fabric and tension created by the unfused stitching may create channels for matrix resin infusion during manufacture.

  • Patent number: 7718101
    Abstract: A process for producing a friction material based on a sheet-like carbon fiber woven fabric for wet-friction elements, such as clutch linings or synchronizing ring linings. The woven fabric of carbon fibers is impregnated with a binder, in particular with a resin, to form a binder-impregnated fiber material. The prepreg is cured for a curing period under a curing temperature which is elevated with respect to the ambient temperature and is pressed mechanically on its surfaces with a pressing mold before the start and/or at least during part of the curing period.

  • Patent number: 7695664
    Abstract: A production method for molding includes a. a first molding: depending on a shape to be molded, implementing a die feed-in on soft cloth, with the plastic that is injected in being fused and set with the cloth, for serving as a substrate layer; b. punching and trimming: punching and trimming the plastic that has been set to form a base; c. a second molding: implementing a second die feed-in on the base of a shaped product, with the injected-in plastic being fused and set with a surface of the base, to form the needed shape; d. tailoring and trimming: tailoring and trimming an edge interface between two layers of the assembled plastic to form a shaped product of a double-layer plastic on the soft cloth.

  • Patent number: 7655168
    Abstract: Tools for manufacturing composite parts and methods for using such tools are disclosed herein. A method in accordance with one aspect of the invention includes manufacturing a fiber-reinforced resin part from a plurality of fibers positioned on a tool having a female mold surface. The mold surface can include a first side region, a second side region, an interior region between the first and second side regions, and transition regions between the first and second side regions and the interior region. The method includes positioning a compaction tool over the mold surface. The compaction tool includes a first pressing device and a second pressing device carrying the first pressing device. The method further includes pressing a first portion of the fibers against the transition regions with the first pressing device without generally compacting the portions of the fibers outboard of the transition regions.

  • Patent number: 7649953
    Abstract: The present invention achieves differential transmit diversity and related diversity reception schemes transmit symbol constellations which are extended to multiple levels. Heretofore, a group of transmission bits is divided into a first sub-group of transmission bits and a second sub-group of transmission bits. Then, the first sub-group of transmission bits is mapped (14) onto constellation points of a differential transmit diversity coding scheme from an orthogonal design for coding of the first sub-group of transmission bits. Then, after differential encoding of the constellation points (32, 34, 36, 40) a length of the transmission symbol vector is scaled (38) for coding the second sub-group of transmission bits. Therefore, the present invention overcomes restrictions implied through unit length requirements for previously known differential transmit diversity schemes from orthogonal designs.

  • Patent number: 7531121
    Abstract: The invention provides a method for simultaneously forming a surface texturing pattern (embossed pattern) on the surface of an FRP product when manufacturing the FRP product by hot-pressing a prepreg material. A prepreg material 2 is a woven sheet formed by weaving a weft 10 and a warp 20 which is impregnated with thermosetting resin 40. A release film laminate 100 formed by sandwiching an adhesive film 130 between release films 110 and 120 is placed on a surface to be provided with surface texturing, before subjecting the same to hot-pressing. The softening temperature of the adhesive film 130 is close to the curing temperature of the thermosetting resin 40, so as to allow the thermosetting resin 40 to be pushed into the space between hard FRP fibers during hot-pressing and to form the surface texturing pattern on the surface of the member.
