  • In-situ, multi-stage debulk, compaction, and single stage curing of thick composite repair laminates
    Patent number: 9034137
    Abstract: A method for fabricating a repair laminate for a composite part having an exposed surface includes applying a bonding material to the exposed surface and forming an uncured ply stack assembly on the bonding material. The uncured ply stack assembly is formed by forming and compacting a series of uncured ply stacks. The ply stack assembly and bonding material are then cured.
    Type: Grant
    Filed: November 26, 2008
    Date of Patent: May 19, 2015
    Assignee: Textron Innovations Inc.
    Inventors: Denver R. Whitworth, Vance N. Cribb, Dumitru R. Jitariu
  • Multi-stage debulk and compaction of thick composite repair laminates
    Patent number: 8382924
    Abstract: 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.
