The hollow glass bead (HGB) filled poly(acrylonitrile–butadiene–styrene) copolymer (ABS) composites were prepared by means of a twin‐screw extruder. The HGB surface of was treated using a silane coupling agent, and the filler volume fraction was range from 0 to 15%. The impact strength ( σ I ) of the ABS/HGB composites was measured at room temperature. On the basis of the impact fracture surface SEM photograph, the impact fracture surface fractal dimension ( D s ) of the composites was measured, respectively, by means of the pixel‐covering method and projective‐covering method and an image processing software, to investigate the relationship between the D s and σ I of the composites. The results showed that the σ I was related closely to D s : σ I increased with an increase of D s , and the relationship between them could be described by an exponential function. Furthermore, the D s measured by the pixel‐covering method were from 1.6232 to 1.7313, while those measured by the projective‐covering method were from 2.5174 to 2.5752.
