ABSTRACT:
Methods of making continuous length articles of reinforced plastic material includes passing rovings of temperature resistant material through a crosshead extruder to impregnate the rovings with a thermoplastic polymer under high pressure. The impregnated rovings are pulled from the extruder through a die and are cooled and shaped into a void free article having a desired cross-sectional shape.
