The fractal research of the tensile fracture for the grain filled polymer composite material ABS/TiO2

摘要

The fracture surface of the materials often shows statistical self-similarity within a certain scope. The fractal characteristic of the fracture surfaces can be quantitatively described by the fractai dimension. In this paper,the box dimension method is applied to calculate the fractal dimensions of the tensile fracture of the grain filled polymer composite material ABS/TiO2,The relations are established between the tensile mechanical behaviors and the fractal dimensions of the tensile fracture,and the relation between the tensile mechanical behaviors and the weight friction of the grain filled materials,The relation between t the fractal dimensions of the tensile fracture and the weight friction of the grain filled materials for the grain filled polymer composite ABS/TiO2.
