Publication number: 20100314807Abstract: The present invention provides a method for producing a profile from composite fiber material, in particular in the aviation and aerospace field, having the following steps: A preliminary fabric, particularly made of pre-impregnated fiber material, is first packed in a vacuum bag. Then support elements are laid on the packed preliminary fabric to support the latter. The vacuum bag is then supplied with a vacuum. Next, the preliminary fabric is hardened to the profile under the action of heat, in particularly in an autoclave. With the claimed method the support elements can be formed advantageously from favorable material, in particular aluminum, instead of highly expensive nickel-36 steel, since the support elements are uncoupled mechanically from the preliminary fabric in a longitudinal direction by means of the vacuum bag, enabling movement of the support elements in the longitudinal direction relative to the preliminary fabric.Type: ApplicationFiled: November 7, 2008Publication date: December 16, 2010Inventors: Hauke Lengsfeld, Wolfgang Cruys, Roland Brandenburg, René Schroeder, Hans Marquardt

Patent number: 7662333Abstract: A tubesheet is formed at the end of a module containing polymeric material for gas separation, by immersing the end of the module in an epoxy material, or its equivalent. A vacuum, or partial vacuum, applied at or near the opposite end of the module, tends to draw the epoxy material towards the source of the vacuum, and results in a tubesheet having a desired thickness, even though the epoxy material may have relatively high viscosity. The method produces effective tubesheets, while minimizing the degree to which the tubesheet covers the otherwise useful surface area of the polymeric material. The method thus produces gas-separation modules having enhanced productivity.Type: GrantFiled: July 10, 2007Date of Patent: February 16, 2010Assignee: Generon IGS, Inc.Inventors: Frederick L.

Patent number: 7540986Abstract: Side edge portions of a film in which a content of a remaining solvent is at least 30 wt. % are contacted to side parts of first-third rollers with suctioning through suction ducts. Thus a middle portion between the side edge portions is not contacted to the rollers, and the film is transported toward a tenter device in accordance with the rotation of the rollers. In the rollers, each side part of the rollers has a larger diameter of a middle part. At least one of intervals between the neighboring rollers is from 1 mm to 200 mm, and the lapping angle is from 1° to 180°. Toward the middle part of the film, and air is fed in a roller side. The obtained film doesn't have any neither crumples, wrinkle, curl and the like, and foreign materials are hardly adhered. Therefore the continuous film production can be made stably.Type: GrantFiled: March 29, 2005Date of Patent: June 2, 2009Assignee: FUJIFILM CorporationInventors: Toshinao Arai, Hidekazu Yamazaki, Sadanobu Fujimoto

Patent number: 7534387Abstract: Apparatus and methods for processing composite components using an elastomeric caul are disclosed. In one embodiment, a method of curing a prepreg on a mandrel includes providing an elastomeric caul over the prepreg; providing a vacuum bag over the prepreg and the caul, with the caul between the prepreg and a film of the vacuum bag; and stretching the elastomeric caul over the prepreg while drawing down the vacuum bag over the caul. The caul is stretched to fit snuggly over the prepreg to reduce fiber deformation and wrinkling during curing.Type: GrantFiled: February 25, 2004Date of Patent: May 19, 2009Assignee: The Boeing CompanyInventors: Grant C. Zenkner, Michael P. Thompson, Stanley F. Polk

Publication number: 20090075545Abstract: A method and system for aligning nanotubes within an extensible structure such as a yarn or non-woven sheet. The method includes providing an extensible structure having non-aligned nanotubes, adding a chemical mixture to the extensible structure so as to wet the extensible structure, and stretching the extensible structure so as to substantially align the nanotubes within the extensible structure. The system can include opposing rollers around which an extensible structure may be wrapped, mechanisms to rotate the rollers independently or away from one another as they rotate to stretch the extensible structure, and a reservoir from which a chemical mixture may be dispensed to wet the extensible structure to help in the stretching process.Type: ApplicationFiled: July 9, 2008Publication date: March 19, 2009Inventors: David S. Lashmore, Robert Braden, Anastasios John Hart, John Welch
