Patent number: 11325282Abstract: Methods of manufacturing composite workpieces that include positioning a heat-generating element proximate to an uncured composite workpiece, triggering the heat-generating element to produce an exothermic chemical reaction or exothermic physical reaction so that the temperature of the uncured composite workpiece is raised to a predetermined first temperature, and curing the composite workpiece while it is at a temperature that is at least the predetermined first temperature.Type: GrantFiled: July 1, 2019Date of Patent: May 10, 2022Assignee: The Boeing CompanyInventors: Xiaoxi Wang, Gary Ernest Georgeson, Jonathan A. Santiago

Patent number: 11298892Abstract: Methods of manufacturing composite workpieces that include adding an expandable element to an internal volume of a constraining container proximate to a uncured composite workpiece supported on a rigid form, where the expandable element is configured to expand when a predetermined change is produced in an attribute of the expandable element; expanding the expandable element by producing the predetermined change in the attribute of the expandable element, so that an expansion of the expandable element applies pressure to the workpiece supported on the rigid form within the internal volume, and curing the composite workpiece while the resulting pressure is applied to the workpiece supported on the rigid form.Type: GrantFiled: July 1, 2019Date of Patent: April 12, 2022Assignee: The Boeing CompanyInventors: Jonathan A. Santiago, Xiaoxi Wang, Gary Ernest Georgeson

Patent number: 11292208Abstract: Composite fabrication system and associated methods. In one embodiment, a composite fabrication system comprises a molding tool that includes a forming surface at least partially disposed within a constrained space, and a foamable material that expands inside of the constrained space to form an expanded material that presses a layup of one or more composite layers against the molding tool. The composite fabrication system further comprises a curing device configured to cure the layup to form a composite part, and a cutting wire embedded in the constrained space that is heated and configured to cut the expanded material into pieces that are removable from the constrained space.Type: GrantFiled: June 21, 2019Date of Patent: April 5, 2022Assignee: The Boeing CompanyInventors: Gary E. Georgeson, Xiaoxi Wang, Jonathan Santiago

Publication number: 20210187876Abstract: Methods of recovering and/or recycling expanded polymer tooling, the methods including collecting expanded polymer tooling, reducing the collected expanded polymer tooling into smaller particles, treating the reduced expanded polymer tooling in order to yield an at least partially purified recovered polymer composition, and then collecting the at least partially purified recovered polymer composition. The at least partially purified recovered polymer composition can then be used to form new expandable polymer tooling.Type: ApplicationFiled: December 19, 2019Publication date: June 24, 2021Applicant: The Boeing CompanyInventors: Xiaoxi Wang, Gary Ernest Georgeson, Jonathan A. Santiago

Publication number: 20210107238Abstract: A composite laminate stiffener is formed to contour with reduced ply wrinkling using constrained creep forming. The tooling apparatus is provided with flexible cauls which constrain the stiffener during the contour forming process. The creep forming is carried out at a slow enough rate so that friction or shear resistance between the resin and fibers of the plies remains low enough that slippage can occur and significant compression stresses are not generated rate, allowing relaxation of residual stresses in the stiffener.Type: ApplicationFiled: October 14, 2019Publication date: April 15, 2021Inventors: Gagandeep Saini, Lisa Christina Carlson, Kurtis Shuldberg Willden, Brian James Smith, Jonathan Santiago

Patent number: 10960619Abstract: Disclosed herein is a method of repairing surface damage in an exterior surface of a hollow bladder, made of a cured elastomer. The method comprises placing first strips, made of an uncured elastomer, at least partially within the surface damage in the exterior surface of the hollow bladder in a side-by-side arrangement. The method also comprises sealing the surface damage, the first strips, and a portion of the exterior surface surrounding the surface damage in a vacuum bag. The method further comprises reducing pressure within the vacuum bag relative to outside the vacuum bag. The method additionally comprises while the pressure within the vacuum bag is reduced, heating the first strips from within the vacuum bag to cure the first strips.Type: GrantFiled: April 8, 2019Date of Patent: March 30, 2021Assignee: The Boeing CompanyInventors: Jonathan A. Santiago, Michael A. Lee, Kin Ung, John D. Morris
