| Abstract: |
| The dynamic fatigue process of NR and BR/NR（70/30）compounds with different carbon blacks was qualitively and quantitively investigated by using the rupture mechanism. The dynamic fatigue process of rubber compounds was described based on the molecular theory，and the S-N curves were analysed and compared combining with the rupture characteristic parameters β and C0.The results showed that for three different rubber compounds reinforced with HAF，ISAF and SAF respectively，the crack growth resistance deteriorated，but the potential defects in rubber compound decreased as the particle size of carbon black reduced. |
