STÉPHANIE PORTET has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for producing a complex composite part, in particular having a thermoplastic matrix
    Patent number: 10807315
    Abstract: A method for manufacturing a composite part with continuous fiber reinforcement and a polymer matrix from a composite preform. On one of the faces of the composite preform, a demarcated layer of thermoplastic polymer is deposited using an additive manufacturing method.
    Type: Grant
    Filed: December 31, 2015
    Date of Patent: October 20, 2020
    Assignee: DAHER AEROSPACE
    Inventors: Stéphanie Portet, Julie Vaudour
  • Method for preparing the laying up and forming of a composite preform
    Patent number: 10486376
    Abstract: A method for making a first ply for laying up a fibrous preform on a tool. An attachment zone is made on the laying up surface of the tool. The zone is integral with the laying up surface of the tool. A polymer is deposited by additive manufacturing on the surface of the tool. The polymer deposit passes on the attachment zone. The first ply is laid up by activating the tackiness of the polymer deposited using additive manufacturing, so as to make the deposited fibers adhere to the material deposited by additive manufacturing.
