The surface of diatomite particles was treated by a silane coupling agent, and the diatomite filled polypropylene (PP) composites with a volume fraction range of the filler from 0 to 15% were prepared by means of melt blending in a twin-screw extruder. The impact strength of the composites was measured at room temperature. The impact fracture surface fractal dimensions of the composite systems were measured using a projective-covering method, and a relationship between the fractal dimension and the impact strength of the composites was investigated. The results showed that the measured surface fractal dimension of the specimens was in a range from 2.4754 to 2.5230, and the fracture surface fractal dimension is an exponential function of the impact strength of PP/Diatomite composites.
