摘要：
Wollastonite-reinforced polypropylene composites were prepared by using tri-screw dynamic compounding extruder and the effect of screw elements combination on the mechanical performance of polypropylene/wollastonite composites was investigated. The results showed that turbine mixing elements are beneficial to distribution mixing and the effect of interleaved arrangement is better than that of continuous arrangement. Compared with the other two screw configurations, interleaved arrangement of turbine mixing elements can effectively modify the distribution and orientation of wollastonite in matrix and compatibility between wollastonite and polypropylene matrix. Accordingly, there is an improvement in the mechanical properties of composites.
