Cerium oxide (CeO 2 ) modified natural rubber (NR) exhibits good mechanical properties, such as high abrasion resistance, high tear strength and good thermal aging and creep resistance. Rubber components are often subjected to long-term cyclic loading in service. Therefore, fatigue performance needs to be considered for their application. In the investigations, tensile properties and fatigue properties of CeO 2 modified vulcanised NR under uniaxial loading were investigated. The fatigue tests were carried out under constant cyclic strain range at room temperature. Results showed that the CeO 2 modified NR demonstrated higher elastic modulus and larger elongation than that of unmodified rubber, which were related to the enhanced interaction and bonding force of rubber chains by CeO 2 additive. Moreover, a remarkably enhanced fatigue life could be achieved in the CeO 2 modified NR. The internal friction and impact in the rubber matrix was relieved by CeO 2 additive, which can reduce the hysteresis loss during cyclic loading, resulting in improved fatigue resistance in CeO 2 modified vulcanised NR.
