Study on Wet-Skid Resistance of Tire Tread Compound with Bionic Coupling

Abstract

This paper adopts the bionics method, takes the honeycomb shape with typical characteristics as the bionic prototype, and discusses the complete bionic coupling design method of the tire tread compounds. Through the analysis of the honeycomb structure and arrangement, the mechanism of wear resistance and wet-skid resistance was found. Combining the characteristics of automotive rubber materials, a tire tread compounds formula with strong abrasion resistance and a tire tread compounds formula with high wet-skid resistance were designed, and the wear-resistant tread materials and high-slip-resistant tread-tread materials were respectively The designed biomimetic model was prepared into a wear-resistant bionic unit and a wet-sliding bionic unit, and then the bionic structure of two kinds of tire tread compounds was optimized by using a press molding method to form a composite bionic tire tread compounds. The experimental results show that the mechanical properties of the composite bionic tire tread compounds are between the wear-resistant tire tread compounds and the anti-slip tire tread compounds, and the wear resistance increases with the increase of the length of the hexagonal side, and the wet-skid resistance The sliding performance decreases with the increase of the hexagonal side length.
