Abstract

Abstract: Influence of different corotating twin screw extruder elements including kneading block，hexagonal prism and variable gap rotor on the length of glass fiber polypropylene composite was studied by numerical simulation and experiment. It showed that with increasing shear effect of screw elements, the average length of glass fiber in products decreased, both the tensile and impact strengths of polypropylene composite decreased.

Key words: polypro pylene, glass fiber, kneading twin-screw extruder;element
