Patent number: 8592024Abstract: A method of restoring a section of a composite includes the steps of removing an undesirable section of a perforated composite and depositing a repair material in the location of the removed, undesirable section. The repair material is then cured. Before completing the curing step, one or more opening are formed through the repair material to produce one or more perforations through the repair material upon completing the curing step.Type: GrantFiled: May 26, 2006Date of Patent: November 26, 2013Assignee: United Technologies CorporationInventors: Daniel M. Stadtlander, William Bogue

Patent number: 8454775Abstract: A method of repairing delaminated plies of a composite includes drilling a plurality of holes in the plies, stitching one or more tows into the plurality of holes, and tensioning the tows. The holes are disposed across an area of the plies that is delaminated. The method introduces a resin into the area of the plies that is delaminated and cures the resin. Curing of the composite can be performed prior to the stitching and the tensioning of the one or more tows and can be performed by the tensioning of the one or more tows. Optionally, one or more additional plies can be applied to the repaired area and/or a portion of the one or more tows that extends above a surface the plies can be removed.Type: GrantFiled: July 29, 2011Date of Patent: June 4, 2013Assignee: United Technologies CorporationInventor: Daniel M. Stadtlander

Patent number: 8128100Abstract: A laminate air seal for a gas turbine engine includes at least one fabric layer made of fiberglass, ceramic fiber, basalt and/or carbon, and a polymeric resin that is stable at an operating temperature of the gas turbine engine. The resin may be preimpregnated into the fabric layers, or introduced into the fabric during assembly and formation of the laminate. The resin may be polyimide, bismaelimide (BMI) or cyanate ester. A particular resin selected may depend, in part, on the operating temperatures in that region of the gas turbine engine. In some embodiments, the laminate seal may include a coating to increase lubricity of the seal. In one embodiment, the laminate air seal is used to seal a gap between a pylon fairing and an exhaust nozzle of the turbine engine.Type: GrantFiled: December 5, 2007Date of Patent: March 6, 2012Assignee: United Technologies CorporationInventors: William F. Bogue, Daniel M. Stadtlander, Charles R. Watson

Patent number: 7857026Abstract: The present invention relates to a method for bonding a component, such as a bushing, into a part, such as a panel. The method broadly comprises attaching a vacuum chamber to a surface of the part, seating the component into a slot in the part, and applying an adhesive material about a circumference of the component while drawing a vacuum in the vacuum chamber to allow the adhesive material to flow between the part and the component.Type: GrantFiled: September 22, 2005Date of Patent: December 28, 2010Assignee: United Technologies CorporationInventor: Daniel M. Stadtlander

Publication number: 20090165926Abstract: A method and system is described herein for using a polyimide adhesive to bond a first metal layer to a second metal layer used in a gas turbine engine. The polyimide adhesive may be a film or a paste and is able to withstand operating temperatures in excess of 600 degrees Fahrenheit (315 degrees Celsius). In an exemplary embodiment, the second metal layer is an outer face skin of an exhaust nozzle and the first metal layer is a metal doubler configured to cover a damaged portion of the outer face skin. In some embodiments, the first and second metal layers may be formed of titanium.Type: ApplicationFiled: October 24, 2007Publication date: July 2, 2009Applicant: United Technologies CorporationInventors: Daniel M.
