Mechanical testing revealed a significant synergistic reinforcement between GO/CNT and CB in NR composites. The improved dispersion of GO/CNT hybrid fillers and CB in the NR matrix was characterized by transmission electron microscopy (TEM). Through the fatigue test, the GO/CNT/CB/NR composites showed excellent fatigue crack growth resistance and low heat build-up compared to CB/NR composites. These properties provide the NR composites with better applications in industry.RSC advancesSynergistic effect of CB and GO/CNT hybrid fillers on the mechanical properties and fatigue behavior of NR composites.PMC907890951333003Wu JHuang CZhu YFu XLuo MHuang GXie ZWei LZhou JfalseSynergistic effect of CB and GO/CNT hybrid fillers on the mechanical properties and fatigue behavior of NR composites.In this paper, graphene oxide (GO) and carbon nanotube (CNT) hybrid fillers were used to replace partial carbon black (CB), and GO/CNT/CB/NR composites were prepared with excellent crack growth resistance, low heat build-up and superior mechanical properties.
