| 摘 要： | 考察了滑石粉填充PP材料颗料分布的分形特性，提出了用分形维数D定量描述复合材料第二相颗粒在基体中的分散状况，通过对比D与冲击强度的关系，发现不同填充体系均存在一临界Dc值，在此分形维数下冲击强度发生转折。同时，通过测定材料冲击断面的粗糙度参量Rs，结果显示Rs同样也会发生与冲击强度相对应的转折变换。 |

| Abstract: | The fractal distribution of particle in PP/talc materials was researched. The fractal dimention D was used for a quantitative parameter to express the distribution condition of filling particle in composite materials. Through the contrast of fractal dimention D and notch impact strength, there existed a critical value-- D c with different filling system, under the criticai value, the inversion change was found with the notch impact strength. At the same time, through the measurement of fracture roughness parameter( R s), it was showed that the same transformation rule also appeared with R s corresponding to the notch impact strength. But the distribution fractal dimention D is not the unique affect factor, the particle size and the filling content can also affect the impact properties. |
| Keywords: | PP fractal distribution particle filling fracture roughness parameter |
