| Abstract: |
| The fatigue life of NR/BR(70/30) vulcanizates cured with conventional，semi-efficient or efficient curing systems and possessing the same apparent crosslinking density was investigated，the fatigue parameters β and C0 of the said 3 vulcanizates were compared to each other，and the curve equations for describing the fatigue life of the vulcanizates cured with 3 different curing systems were fitted to the exponential function model.The equations with the maximum relative error only up to -6.25% and the correlation factors greater than 0.953 5 were suitable to describe the dynamic fatigue process of NR/BR vulcanizates cured with different curing system. |
