摘　　要：研究氧化石墨烯(GO)对炭黑/天然橡胶复合材料性能的影响。结果表明:加入少量GO,可以明显增强复合材料的填料网络结构,提高物理性能和高撕裂能下的耐疲劳性能;对于经历不同疲劳程度后的复合材料,在疲劳前期GO的加入促进了填料的分散,从而减小复合材料的裂纹扩展速率,提高耐疲劳性能。The effects of graphene oxide（GO） on the fatigue resistance of carbon black/NR composites were investigated. The results showed that,by adding a small amount of GO,the filler network structure of the composite was significantly strengthened,the physical properties and fatigue resistance at high tearing energy were improved. The addition of GO promoted the dispersion of fillers in the early stage of fatigue,thus the crack growth rate of the composite decreased,and the fatigue was improved.
