摘　　要：目前,电动汽车(EV)轮胎胎面磨损速度比内燃机(ICE)轮胎快30%+。因此需要“绿色”复合材料,因为它比一般轮胎具有更好的燃油经济性和更少的炭黑含量。Molecular Rebar的使用,减少了油和二氧化硅的用量,使轮胎性能得到明显改善。研究证明,Molecular Rebar材料可以增加与聚合物基体的结合,提供独特的增强和滞后性能优势的组合。当用作为二氧化硅的替代物,并对油的浓度进行一些调整时,功能性MR为电动车辆轮胎提供了所需的性能增强,如改善DIN耐磨性和降低滚动阻力。Currently,the tread wear rate of electric vehicle(EV)tires is more than 30%faster than that of internal combustion engine(ICE)tires.Therefore,a"green"composite material is needed because it has better fuel economy and less carbon black content than regular tires.The use of Molecular Rebar reduces the amount of oil and silica used,resulting in a significant improvement in tire performance.Research has shown that Molecular Rebar materials can increase the binding with polymer matrices,providing a unique combination of enhanced and hysteresis performance advantages.When used as a substitute for silicon dioxide and with some adjustments to the oil concentration,functional MR provides the required performance enhancements for electric vehicle tires,such as improving DIN wear resistance and reducing rolling resistance.
