“…Chen et al12, 13 studied the wear behavior of short‐fiber‐reinforced polymer and found that the self‐lubricating thin film that forms on the contact surface during the wearing process played a dominate role in suppressing transverse cracks. Uchiyama et al7, 8 showed that fiber orientation had an obvious effect on the wear property of a short‐fiber‐reinforced rubber composite. The effect of decreasing the wear loss of rubber materials containing ZnO whisker can be explained by several aspects.…”

“…The wear behaviors and mechanisms of polymer materials have attracted more and more attention 6. Uchiyama et al7, 8 studied the influence of short fibers and their orientations on the wear property of rubber composites, and their results indicate that fiber orientation has a strong effect on specific wear rates. In the experiments the short fibers were designed to specific orientations, and clearly the composites had anisotropy.…”

Zinc oxide whisker with a tetrapod shape was treated with a coupling agent using an orthogonal design and was mixed into the substrate of natural rubber to obtain the composites. The results of the experimental tests show that the tensile strength of the composites progressively increases with an increased amount of the related whisker. The experiments also indicate that the rubber reinforced by the tetrapod-shaped ZnO whisker is distinct isotropy. The wear tests demonstrate that the composites containing ZnO whisker appear to have good wear-resistance behavior.

“…In a previous work, we reported on the effect of the dispersion and orientation of short fibers in SFRR 6. The friction and wear properties of SFRRs were also studied when they were rubbed against abrasive cloth 7. The friction coefficients of SFRRs were less than those of the unfilled rubber, and scarcely dependent on the orientation of the fiber during the abrasive wear.…”

ABSTRACT:The friction coefficient of short-fiber-reinforced rubber (SFRR) was examined under dry and wet conditions. When the unfilled rubber is rubbed against a dry glass disk, the friction coefficient is higher than that of the SFRR and decreases as contact pressure increases. On the other hand, the friction coefficient for the SFRR is relatively low, and decreases slightly with the increase of contact pressure. When the unfilled rubber is rubbed against a silicone oil-lubricated glass disk, the friction coefficient is lower than that in a dry condition, and decreases with increasing sliding speed to reach a minimum value. After that, it increases slightly with the increment of the sliding speed at the sliding speed range examined. The friction coefficient of the SFRR on the wet surfaces is lower than that of the unfilled rubber at low sliding speeds. With an increase in speed, the friction coefficient initially decreases, and then reaches a minimum value. After that, it increases with the increment of sliding speed. The minimum for the unfilled rubber and the SFRRs shifts toward lower sliding speeds when the contact pressure is increased. Therefore, under the condition of mixed lubrication at low speeds, the friction coefficient at low contact pressure is higher than that at high contact pressure. This trend is distinguishable as the fiber content of the SFRR is increased. The phenomena at high contact pressures arise from the reduction of effective surface roughness, as the unfilled rubber deforms and the SFRRs deflect because of the applied load.
