Graphene oxide (GO) sheets and carbon nanotubes (CNTs) are of nanometer size and offer large shape factors which are beneficial in reducing crack propagation rates of composites when used in carbon black (CB) reinforced natural rubber (NR), thereby prolonging the service lives of rubber composites. In this research, CNT-CB/NR and GO-CB/NR composites were prepared by partially replacing CB with one-dimensional CNTs and two-dimensional flaky graphene oxide GO, respectively. The results showed that the complex filler dispersion in NR matrices was improved due to the isolation effect between the different fillers. The strain-induced crystallization (SIC) ability of CB/NR was effectively enhanced by the addition of both GO and CNT. The modulus at 100% strain and tear strength of the composites were also improved. More branching and deflections were observed at the crack tips of the composites and both effectively hindered crack propagation in the materials. Under uniaxial and multi-axial cyclic loading, the fatigue lives of CNT-CB/NR and GO-CB/NR composites greatly increased when compared with the fatigue lives of CB/NR composites. The GO-CB/NR composites exhibited evident advantages in respect of fatigue resistance and durability among the three composites.

“…The crack growth rates of the composites were determined using a crack extension analyzer (DMA + 1000, METRA VIB, Lyon, France) at 20 Hz and 25 °C. The dimensions of the samples were 2 mm × 6 mm × 40 mm, and the precut depth was 1.5 mm [ 36 ]. Under pure shear conditions, the tearing energy of the rubber composites can be calculated using the following equation:

where G is the tearing energy (J/m 2 ), E f is the input energy (J), S is the cross-sectional area of the sample (m 2 ), and L and e are the width (m) and thickness (m) of the sample, respectively.…”

Fibrous carbon nanotubes (CNTs) and lamellar graphene oxide (GO) exhibit significant advantages for improving the fatigue properties of rubber composites. In this work, the synergistic effect of CNTs and GO on the modification of the microstructure and fatigue properties of natural rubber (NR) was comprehensively investigated. Results showed that CNTs and GO were interspersed, and they formed a strong filler network in the NR matrix. Compared with those of CNT/NR and GO/NR composites, the CNT-GO/NR composites showed the smallest crack precursor sizes, the lowest crack growth rates, more branching and deflections, and the longest fatigue life.

Herein, the carbon black/graphene oxide/natural rubber composites (CB/GO/NR) with different crosslink networks were prepared through the latex co-precipitation approach. Meanwhile, the type of crosslinks on the crack propagation resistance and fatigue life in different vulcanized systems were investigated. As a result, CB/GO/NR composites dominated by polysul de in conventional vulcanization (CV) system exhibited the improved tear strength (71.6 KN/m) and lowest crack growth rate (64.1 nm/cycle), the developed crosslink network and polysul de based crosslink structure in CV system were the key factors to improve the crack propagation resistance. In addition, the relationship between viscoelasticity and dynamic crack propagation behavior of CB/GO/NR was studied, and the CV system had the lowest loss compliance modulus( J "), thus more energy dissipation occurred in the crack propagation region and the crack propagation resistance of CV system was improved. Importantly, this work can provide the guideline for designing the rubber-based composites in the practical engineering applications.
