摘要：
A method of preparing filled, modified and fiber reinforced thermoplastics is distinguished by the fact that polymer as matrix material together with blend polymer is fed to a twin screw extruder in a single manufacturing process, filler being supplied through a feeder device after the melting. Then fiber rovings are fed in and cut into long fiber sections in a fiber incorporation zone.
