Patent number: 8168023Abstract: Composite sections for aircraft fuselages and other structures, and methods and systems for manufacturing such sections, are disclosed herein. A method for manufacturing a shell structure in accordance with one embodiment of the invention includes applying composite material to an interior mold surface of a tool to form a skin extending 360 degrees around an axis. The method can further include positioning a plurality of stiffeners on an inner surface of the skin. After the stiffeners have been positioned, a vacuum bag can be installed over the stiffeners and evacuated to press the stiffeners and the skin outwardly against the interior mold surface of the tool. Next, the skin/stiffener combination can be cocured to bond the stiffeners to the skin and harden the shell structure.Type: GrantFiled: February 6, 2009Date of Patent: May 1, 2012Assignee: The Boeing CompanyInventors: Michael R. Chapman, Robert M. Watson, Donald A. Anderson, Marc J. Piehl, Joseph L. Sweetin, Douglas L. Grose

Publication number: 20110290472Abstract: Embodiments of the present invention provide a process for manufacturing swellable packers with reinforcing fabrics and associated products used for sealing off chambers within well bores. According to one embodiment, the swellable packer is formed around a pipe by embedding a sheet of the reinforcing fabric within layers of a swellable polymer wrapped around the pipe. A sheet of reinforcing fabric is situated near each end of the swellable packer. Thus, as exposure to oil or water will cause the swellable packer to expand, the reinforcing fabric will initially retard swelling at the ends to allow for greater initial swelling along the center portion. The reinforcing fabric also strengthens the polymer to resist tearing or breakage caused by the flow of oil or water. A pair of swellable packers according to embodiments of the present invention can be placed on a pipe and placed within a bore and exposed to oil or water to create a pressurized chamber.Type: ApplicationFiled: May 27, 2011Publication date: December 1, 2011Inventors: Dennis Doweidt, John Yackey

Patent number: 8066838Abstract: A method of fabricating a composite tubular member includes providing a mandrel having a central longitudinal axis and wrapping a plurality of composite fiber layers around said mandrel wherein the longitudinal axis thereof is oriented at a first angle with respect to the longitudinal axis of said mandrel. The composite tubular member produced does not have any longitudinal seams and is thus considerably stronger and more durable than prior art composite tubes.Type: GrantFiled: May 9, 2008Date of Patent: November 29, 2011Assignee: Hillerich & Bradsby Co.Inventor: George W.

Method for producing tubular body made of fiber reinforced resin and tubular body produced by method
Patent number: 8057617Abstract: A method for producing a tubular body includes a step of winding at least one of winding bias prepregs, at least one of straight prepregs, and at least one of hoop prepregs round a core. At the winding step, after the hoop prepreg and/or the hoop prepreg are adherently layered in advance on a base prepreg consisting of the bias prepreg or the straight prepreg to form a laminate and/or a laminate, the laminate and/or the laminate are wound on the core so that the hoop prepreg and/or the hoop prepreg are wound on the core integrally with the base prepreg or the base prepreg.Type: GrantFiled: March 14, 2008Date of Patent: November 15, 2011Assignee: SRI Sports LimitedInventor: Hiroaki Fujimoto -

Publication number: 20110132524Abstract: Poles of this invention have an annular body with a wall structure comprising a number of fiber reinforced resin layers, which can be positioned to form an inside and/or outside portion of the wall structure. A portion of the layers are oriented longitudinally within the wall structure, and the wall structure also includes radially-oriented fiber reinforced resin layers. The pole includes one or more layers or a core of a composite material or polymer mortar disposed within one or more locations of the wall structure, e.g., as an intermediate layer and/or as part of the wall inside and/or outside portion. The pole can include an outside surface resistant to ultra violet radiation. Poles of this invention can be formed using a continuous process on a rotating mandrel, making use of differently positioned stations to form the different portions of the pole as the fabrication is moved axially along the mandrel.Type: ApplicationFiled: February 17, 2011Publication date: June 9, 2011Applicant: AMERON INTERNATIONALInventors: Ralph S.
