| Abstract: |
| The tension fatigue property,dynamic fatigue failure property at high or low strain and rupture parameter β of BR/NR blend with various antioxidants were determined by test to obtain a regressive equation which could be used to predict the fatigue life with any tension ratio λ.It was found that the predictive fatigue life was basically in accordance with the measured one.The characteristics in rupture process on ruptured cross-section was analysed .The test results showed that the amine-type antioxidants were effective to improve the fatigue life of BR/NR blend. |
