  • Patent number: 6190586
    Abstract: The invention comprises a method for creating a billet for molding a part. A plasticator is loaded with long reinforcing fibers and materials, such as a polyester, a carbocyclic, thermoplastic polymers or mixtures thereof, and heated to a predetermined temperature. The feed is then blended and plasticated to form a molten suspension. Pressure and shear within the plasticator is controlled to provide a process that provides a moldable billet with the length of the reinforcing fibers generally preserved through the plasticating and molding operation.
