Gregory Scott O'BRIEN 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).

  • High strength polyvinylidene fluoride based sized reinforcing fibers
    Patent number: 11840800
    Abstract: The invention relates to sized reinforcing fibers that comprise a reinforcing fiber sized with a fluoropolymer. The fluoropolymer is functionalized and/or the reinforcing fiber is sized with a compatible functional non-fluorinated polymer that is compatible with the fluoropolymer. Functionalization of the fluoropolymer or the compatible non-fluorinated polymer provides enhanced properties, such as increased adhesion to the reinforcing fiber.
    Type: Grant
    Filed: July 16, 2018
    Date of Patent: December 12, 2023
    Assignee: Arkema Inc.
    Inventors: Gregory Scott O'Brien, Ramin Amin-Sanayei, Saeid Zerafati, James T. Goldbach
  • High strength polyvinylidene fluoride composite
    Patent number: 11542658
    Abstract: The invention relates to fluoropolymer composites having a fluoropolymer matrix containing a functionalized fluoropolymer composition, and reinforced with fibers. The fibers can be chopped fibers, long fibers, or a mixture thereof, and the fluoropolymer matrix preferably is based on polyvinylidene fluoride. Any type of fibers, sized or unsized may be used with the functionalized fluoropolymer matrix composition to form the fluoropolymer composite.

  • High strength polyvinylidene fluoride based reinforced compounds
    Patent number: 11136450
    Abstract: The invention relates to the use of chopped fibers in thermoplastic composite compounds, and in particular to thermoplastic fluoropolymer compounds. The fluoropolymer matrix contains thermoplastic fluoropolymers that have been grafted with a carboxylic polar functionality, such as KYNAR ADX® polymer from Arkema. The chopped fiber—grafted fluoropolymer composite has increased tensile and flexural strength compared to fluoropolymer compounds that contain no grafted carboxylic grafted fluoropolymer.
