| Abstract: | The PP/wollastonite/EPDM composites with different volume fraction of rubber and filler were prepared by melt extrusion in a twin-screw extruder. The composites were studied by means of Scanning Electron Microscope (SEM) .Computer Image Analysis (CIA)and mechanical testing methods. The results show that the mechanical properties of the composites were controlled by the component content and morphology. Both the impact strength and modules of the composites can be improved. |
