| Abstract: |
| In this study， carbon nanotube was applied to replace equal weight of carbon black in the SBR composites and the fatigue resistance of the composites in a wide strain range (30%～100%) was investigated.The addition levels of carbon nanotube were 1，2，3 and 4 phr，respectively.The results showed that，under the same strain level，when the addition level of carbon nanotube increased，the fatigue life of the composites was reduced，the fatigue crack growth rate increased，and the sensiti-vity of tearing energy on fatigue crack growth rate of the composites decreased.When the tearing energy was high，the addition level of carbon nanotube had a small effect on the fatigue crack growth rate. |
