  • Composite laminate tooling and method of forming a composite part using the tooling
    Patent number: 10434687
    Abstract: A composite piece tool used to create a composite piece. The tool includes a substrate having a substrate surface, walls disposed on the substrate and extending from the substrate surface in a thickness direction of the composite piece to define opposite locations of longitudinal composite piece ends and composite piece sides, a tooling surface disposed to occupy an entirety of a space delimited by the walls and on which the composite piece formed and a servo controller coupled to the tooling surface and configured to move the tooling surface upwardly and downwardly relative to the substrate surface and walls to form the composite piece.
    Type: Grant
    Filed: December 10, 2015
    Date of Patent: October 8, 2019
    Assignee: SIKORSKY AIRCRAFT CORPORATION
    Inventors: Joshua A. Breon, Mario Dipreta
  • Rotor blade spar formation with automated fiber placement
    Patent number: 10406763
    Abstract: A blade element is provided and includes courses of bias plies continuously machine-wrapped about leading and trailing edges at an angle relative to a long axis of the blade axis and unidirectional plies interwoven in parallel with the long axis between adjacent courses of the bias plies on upper and lower surfaces to promote respective tangential geometries of the bias plies at the leading and trailing edges, the unidirectional plies not extending into the leading and trailing edges.
