The membrane (34) and the reinforcing elements are then positioned under a press consisting of an upper air-filled chamber (1), the lower part thereof comprising a flexible element (4), and a lower water-filled chamber (14), the upper part thereof comprising a flexible element (17). According to the invention, a forming bar (10) is adjustably mounted in the upper chamber (1). When the aforementioned forming bar (10) is adjusted to adopt a particular shape, the different flexible elements can deform at the forming bar and the membrane and the reinforcing elements are hot pressed with a portion corresponding to the forming bar having a three-dimensional shape, thereby defining the form of the fabric produced.Type: GrantFiled: June 25, 2003Date of Patent: January 20, 2009Assignee: Createx S.A.Inventors: Gérard Gautier, Edouard Kessi

Patent number: 7476716Abstract: The invention relates to a process for the production of post-crosslinkable thermoplastic resins by bulk-polymerizing a polymerizable composition (A) comprising (I) a monomer fluid containing a cyclic olefin (?) having two or more metathetical ring-opening reaction sites in the molecule in an amount 10 wt % or above based on the total amount of the monomers or a monomer fluid containing a norbornene monomer and a crosslinking agent, (II) a metathetical polymerization catalyst, and (III) a chain transfer agent; thermoplastic resins obtained by this process; and a process for producing crosslinked resins or crosslinked resin composite materials which comprises laminating such a thermoplastic resin with a substrate at need and then crosslinking the thermoplastic resin. According to the invention, thermoplastic resins which are free from odor due to residual monomers and excellent in storage stability can be efficiently obtained by a simple process of bulk-polymerizing the composition (A).Type: GrantFiled: June 26, 2003Date of Patent: January 13, 2009Assignee: Zeon CorporationInventor: Tomoo Sugawara

Publication number: 20080290191Abstract: An integral composite rocket motor nozzle. The novel nozzle includes a first layer of a first reinforcement material, a second layer of a second reinforcement material, and a common matrix material surrounding the first and second reinforcement materials such that the reinforcement materials and matrix material form a single integral composite structure. In an illustrative embodiment, the first reinforcement material includes graphite fibers for providing structural support, and the second reinforcement material includes glass or quartz fibers for providing thermal insulation on a first side of the first layer. The nozzle may also include a third layer of a third reinforcement material for providing thermal insulation on a second side of the first layer. In a preferred embodiment, the first layer is shaped to form an integrated dome and nozzle structure.Type: ApplicationFiled: November 27, 2007Publication date: November 27, 2008Inventors: Andrew B. Facciano, Robert T. Moore, Kelly J. Sinnock, Scott T. Caldwell

Publication number: 20080286564Abstract: Carbon nanotube interlayer assemblies, methods of manufacturing carbon nanotube interlayer assemblies, and methods of manufacturing composite parts with carbon nanotube interlayer assemblies are disclosed herein. In one embodiment, a method of manufacturing a composite structure in accordance with an embodiment of the invention includes producing a plurality of carbon nanotubes on one or both sides of a substrate, and attaching the substrate to a first fiber layer. The method can further include positioning a second fiber layer adjacent to the first fiber layer to position the plurality of carbon nanotubes between the first and second fiber layers. The method can additionally include infusing the first and second fiber layers with resin, and curing the resin. In one embodiment, the carbon nanotube substrate can be attached to the first fiber layer by melt-bonding. In another embodiment, the carbon nanotube substrate can be attached to the first fiber layer with stitches.Type: ApplicationFiled: May 17, 2007Publication date: November 20, 2008Applicant: The Boeing CompanyInventor: Thomas K.

Publication number: 20080277057Abstract: Composite laminates used in structural applications include an interlayer of soft material that provides damping action to reduce noise and vibration. The interlayer may comprise a viscoelastic material which deforms under stress caused by shock, noise or vibration. A reinforcement may be embedded in the viscoelastic material to maintain the mechanical strength and stiffness of the laminate. The reinforcement may include individual or woven fibers or ridged tubes that provide the interlayer with stiffness.Type: ApplicationFiled: January 23, 2007Publication date: November 13, 2008Inventors: Joshua M. Montgomery, Salvatore L. Liguore, Tuan Q. Cao
