“…The stress of Silica40/AP2 with a strain of about 102% exceeds that of Silica50/AP1 before fatigue, but after 50,000 fatigue cycles, the stress of Silica40/AP2 is higher than Silica50/AP1 from beginning to end. After 50,000 fatigue cycles, the stress–strain curves (0%–150%) of the composites have changed significantly on account of the hysteresis in the reinforcement of the fibers 21 . In Figure 7B, compared with Silica50/AP1 which is also filled with 1 phr AP, the inflection point of the Silica45/AP1 appears at lower strain (0%–150% strain area), and the difference of strain energy (the area surrounded by the stress–strain curves) between Silica45/AP1 and Silica50/AP1 decreases after fatigue, indicating that after adding a small amount of AP, the influence of the decrease in filler content on the reinforcement effect is reduced after fatigue.…”

As the content of silica is reduced, the probability of silica weaking the interface of fiber and rubber matrix is reduced, which was confirmed in SEM figure , showing the synergistic enhancement effect.…”

“…The properties of rubber composites can be improved by filling only a small amount of aramid fiber. 21,22 However, aramid fiber is a rigid material and the surface of aramid fiber is chemically inert and poorly combined with the matrix material. [23][24][25] When subjected to alternating stress, aramid fiber will produce friction with rubber molecular chains and particles in the rubber matrix, causing a lot of heat.…”

The composites with excellent mechanical, low rolling resistance, and low heat build‐up are the potential materials for preparing green tires. In this study, we prepared silica‐natural rubber latex (silica‐NRL) masterbatch, which improved the processing and dispersion properties of silica in the natural rubber, proved by the rheological properties of composites. Furthermore, the idea of partial replacement of silica with low content modified aramid pulp (AP) for preparing hybrid enhanced natural rubber with high mechanical properties and low heat build‐up was put forward and evaluated the feasibility of this strategy. We find that replacing 5 phr silica with 1 phr AP, the performances of the rubber composites were all superior to the composites with only filled 50 phr silica, and replacing 10 phr silica with 2 phr AP, the mechanical and fatigue property was improved remarkably and dynamic heat generation was reduced the most at same time. The strategy of preparing silica‐NRL masterbatch and partial replacement of silica with AP provides a novel reference for the preparation of low heat build‐up green tire.

Energy harvesting systems fabricated from rubber composite materials are promising due to their ability to produce green energy with no environmental pollution. Thus, the present work investigated energy harvesting through piezoelectricity using rubber composites. These composites were fabricated by mixing titanium carbide (TiC) and molybdenum disulfide (MoS2) as reinforcing and electrically conductive fillers into a silicone rubber matrix. Excellent mechanical and electromechanical properties were produced by these composites. For example, the compressive modulus was 1.55 ± 0.08 MPa (control) and increased to 1.95 ± 0.07 MPa (6 phr or per hundred parts of rubber of TiC) and 2.02 ± 0.09 MPa (6 phr of MoS2). Similarly, the stretchability was 133 ± 7% (control) and increased to 153 ± 9% (6 phr of TiC) and 165 ± 12% (6 phr of MoS2). The reinforcing efficiency (R.E.) and reinforcing factor (R.F.) were also determined theoretically. These results agree well with those of the mechanical property tests and thus validate the experimental work. Finally, the electromechanical tests showed that at 30% strain, the output voltage was 3.5 mV (6 phr of TiC) and 6.7 mV (6 phr of MoS2). Overall, the results show that TiC and MoS2 added to silicone rubber lead to robust and versatile composite materials. These composite materials can be useful in achieving higher energy generation, high stretchability, and optimum stiffness and are in line with existing theoretical models.
