The materials or bionic methods available cannot further solve the contradiction between the wear resistance and wet resistance of tire tread compounds. In this study, a convex‐hull bionic tire tread compound was designed and produced according to the difference in wear resistance between two types of tire tread compounds. The effects of the bionic structure on the wear resistance and wet resistance of the tire tread compounds were explored by analyzing the changes in wear loss, wear surface characteristics, and wet friction coefficient. The wear resistance and wet resistance of the convex‐hull bionic tire tread compound were collaboratively improved. The largest increasing rate of wear resistance was 9%, and the largest increasing rates of wet sliding ability on sand paper surface and on smooth glass surface were 3.4% and 4.2%, respectively. The coupling design of materials and bionic structures offers a new way to improve the overall performances of tire tread compounds.

Jute fibres were processed with different types of structures, and these fibres were applied to prepare friction composites through compression moulding. The Structured Jute fibres reinforced Friction composites (SJF) were heat-treated using a heat treatment tank, and the mechanical and tribological properties of the SJF were investigated with a friction-wear tester. The surface morphologies of friction composites were observed using Scanning Electron Microscopy (SEM). The experimental results showed that structured jute fibres could improve impact strength of SJF, but they had no obvious effect on their density and hardness. The friction-wear tests revealed the specimens to present a remarkable fade phenomenon when the test temperature was above 200°C. The presence of the structured jute fibres could decrease the wear rates (V) of SJF when the temperatures were in the range of 250 to 350°C, especially for specimens containing beaded jute fibres and specimens containing dumbbell-shaped jute fibres. They also increased the friction stability and decreased the wear rates of the friction composites. For all specimens, wear rates of the SJF increased with the test temperature. The results of this study could be useful in many applications, such as automobile brake system, clutches and friction gearings.
