  • Composite toughening using three dimensional printed thermoplastic pins
    Patent number: 11203404
    Abstract: A composite article including a plurality of layers each comprising bundles of fibers separated by spaces; pins bonded to a side of at least one of bundles and extending or built through the spaces between the layers; and a resin combined with the layers and the pin. The pins form a physical barrier preventing or reducing propagation of cracks in an x-y plane of the composite article.
    Type: Grant
    Filed: April 19, 2018
    Date of Patent: December 21, 2021
    Assignee: THE BOEING COMPANY
    Inventors: Christopher A. Howe, Kariza Martin, Michelle Louise Gee, Adrian Mouritz
  • Three dimensional printed fibrous interlocking interlayers
    Patent number: 10940648
    Abstract: A three dimensional permeable thermoplastic tape useful for joining of layers of fiber tows (plies) together so as to form highly toughened resin infused structures. In one or more embodiments, the tape is manufactured using three dimensional printing and is applied between layers of fiber tows so as to tack the layers of fiber tows in place and prevent movement of the layers of fiber tows.
    Type: Grant

  • Thermoplastic cellular network toughened composites
    Patent number: 10562262
    Abstract: A composite article including fiber tows and a network including material drawn or pulled between the fiber tows. The network forms a physical barrier reducing propagation of cracks in the composite article. Exemplary structures described herein are the first to use a novel cellular architecture to toughen resin infused composites and create a continuous through thickness reinforcement that does not induce fiber breakage.
