现有的材料或仿生方法不能进一步解决轮胎胎面胶耐磨性和耐湿性之间的矛盾。本研究根据两种轮胎胎面胶耐磨性的差异，设计并生产了一种凸船体仿生轮胎胎面胶。通过分析胎面胶的磨损量、磨损表面特征和湿摩擦系数的变化，探讨了仿生结构对胎面胶耐磨性和抗湿摩擦性能的影响。协同提高凸船体仿生轮胎胎面胶的耐磨性和耐湿性。耐磨性最大提高率为9%，在砂纸表面和光滑玻璃表面的湿滑动能力最大提高率分别为3.4%和4.2%。材料与仿生结构的耦合设计为提高胎面胶的综合性能提供了新的途径。
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.
