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.

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.

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.
