| 中文摘要: |
| 研究屈挠温度和屈挠频率对天然橡胶耐屈挠疲劳性能的影响。结果表明：随着屈挠温度升高，硫化胶的耐屈挠疲劳性能先提高后降低，屈挠疲劳断面的粗脊痕线先增多后减少，脊痕线规整性先降低后提高；随着屈挠频率增大，硫化胶的耐屈挠疲劳性能降低，屈挠疲劳断面的粗脊痕线减少，细脊痕线增多且规整性提高。 |
| 英文摘要: |
| The effect of flexural temperature and flexural frequency on the flexural fatigue resistance of natural rubber was investigated.The results showed that，with the increase of flexural temperature，the flexural fatigue resistance of vulcanizate was improved first and then reduced，the thick ridge lines of flexural fatigue section increased first and then decreased，and the regularity of ridge lines reduced first and then improved.With the increase of flexural frequency，the flexural fatigue resistance of vulcanizate was reduced，the thick ridge lines of flexural fatigue section decreased，the thin ridge lines increased and the regularity was improved. |
