Abstract:
      The Akron abrasion test was carried out on natural rubber（NR）/cis-1，4-polybutadiene rubber（BR） blends with different blending ratios，and the wear debris fractal dimensions of NR/BR blends were characterized and calculated to explore the relationship between wear resistance and wear debris fractal dimensions of NR/BR blends.The results showed that，with the increase of NR/BR blend ratios，the Akron wear amounts of NR/BR blends decreased first and then increased，and the Akron wear amounts of NR/BR blend was the smallest when NR/BR blend ratio was 60/40.The wear debris fractal dimensions of NR/BR blend increased first and then decreased，and the wear debris fractal dimension of NR/BR blend was the largest when NR/BR blend ratio was 60/40，the changing trend of the wear debris fractal dimensions of NR/BR blends was contrary to that of the Akron wears.The higher the degree of agglomeration of the wear debris of NR/BR blend was，the greater the wear debris group fractal dimension was.
