  • Publication number: 20040265558
    Abstract: The present invention discloses the extrusion of a thermally conductive polymer composition containing a continuous core of carbon fiber reinforcing. The material is created in a machine that is configured to hold a spool containing a continuous strand of carbon fiber core material. The carbon fiber strand is unrolled off the spool and is fed into a preheating chamber to bring the temperature of the strand to a pre-designated level. The strand is then fed into a port in an extruding head on a pressure extruding machine. A molten polymer matrix is also fed into the extruding head thereby extruding the polymer matrix onto, around and between the individual carbon fibers contained in the strand. The singular extruded composite strand that emerges from the extrusion head is then cooled and deionized before cutting the composite strand into pellets of a desired length for further processing and use as injection molding feedstock.
