摘要
高分子复合材料的断面形貌呈现出自相似性和自放射性,具有分形特征,可用分形维数来定量描述。文中讨论了结构函数法、像素点覆盖法和投影覆盖法计算高分子复合材料断面的三维分形维数的原理、方法和步骤,对比分析了三种方法的准确性。最后指出了将来的研究方向。
The morphology of fracture surface of polymer composites exhibits self-similarity and self-radioactivity,and is fractal,which can be quantitatively characterized by fractal dimension. In this paper,the principles,methods and procedures of structure function method,pixel coverage method and projection coverage method for calculating 3D fractal dimension of fracture surface of polymer composite were discussed,and the accuracy of the three methods was compared and analyzed. Finally,the future research directions were pointed out.
