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.
