Patent number: 11135824Abstract: A method for fabricating a repair laminate for a composite part having an exposed surface includes applying a release film to the exposed surface and forming an uncured ply stack assembly on the release film. The uncured ply stack assembly is formed by forming and compacting a series of uncured ply stacks. The release film and ply stack assembly is then removed from the exposed surface. A bonding material is then applied to the exposed surface, and the uncured ply stack assembly is applied to the bonding material. The ply stack assembly and bonding material are then cured.Type: GrantFiled: January 2, 2019Date of Patent: October 5, 2021Assignee: Textron Innovations Inc.Inventors: Denver Ray Whitworth, Vance Newton Cribb, III, Dumitru Radu Jitariu

Patent number: 8663396Abstract: A method of cleaning a contaminated composite part, so as to provide a surface suitable for adhesive bonding. The method includes applying a wicking medium adjacent to a surface of the contaminated composite material. Then applying a solvent medium soaked in a cleaning solution adjacent to the wicking medium. Then vapor barrier is applied adjacent to the solvent medium. Next a breather material is applied adjacent to the vapor barrier. Then a vacuum bagging film with a vacuum port is applied and sealed against the composite part. The composite part is then heated and vented to remove contaminates from the composite material.Type: GrantFiled: May 29, 2009Date of Patent: March 4, 2014Assignee: Textron Innovations Inc.Inventors: Denver Ray Whitworth, Vance Newton Cribb, III
