摘要： 为改良汽车轮胎胎面胶的耐磨性能及力学性能，有效提升轮胎的使用寿命，研究了经硅烷偶 联剂与多巴胺进行表面处理后的碳纤维及碳纳米管的用量对复合胎面胶的耐磨性能以及其拉伸强度的 影响。使用二次回归正交设计的方法设计编排试验方案；应用万能试验机及 DIN 磨耗仪测得了橡胶 材料的力学性能及摩擦学性能；采用基于 NSGA-II 改进的多目标优化算法对试验指标进行优化，找 出了原模型的 pareto最优解集并绘制了响应曲面，并得出最佳参数组合。结果表明：当天然橡胶为 82.66 份，碳纳米管为 7.43 份，碳纤维为 6 份，制样后测得的实际磨耗量为139.7 mm3，断裂强度为 20.8 MPa，显示出碳纤维 / 碳纳米管复合胎面胶具有良好耐磨性与拉伸性能。

Abstract: The effect of the amount of carbon fiber and carbon nanotubes treated with silane coupling agent and dopamine on the wear resistance and tensile strength of the compound tread adhesive was studied to improve the wear resistance and mechanical properties of the tire tread to extend its servise life. The experimental scheme was designed and arranged by the method of quadratic regression orthogonal design. Mechanical properties and tribological properties of rubber materials were measured by universal testing machine and DIN wear meter. An improved multi-objective optimization algorithm based on NSGA-II was used to optimize the test indexes. The response surface was drawn and the best combination of parameters was obtained by the Pareto optimal solution set of the original model. The results show that the abrasion loss is 139.7 mm3, and the fracture strength is 20.8 MPa by 82.66 phr （parts per hundred） for natural rubber, 7.43 phr for carbon nanotubes and 6 phr for carbon fiber, showing that the carbon fiber/carbon nanotube composite tread adhesive has good wear resistance and tensile properties.
