摘　　要：研究新型纤维帘线EPT66(简称EPT66)在高性能轿车轮胎冠带层中的应用。结果表明:与锦纶66(简称N66)相比,EPT66的破断力和粘合力增大,收缩率减小、尺寸稳定性提高,各项性能均满足企业标准要求;采用EPT66替代N66作为冠带层材料,符合轮胎生产标准要求;试制的轮胎室内性能满足国家标准要求,安全性和舒适性提高,轮胎使用寿命延长;在保证轮胎生产工艺和冠带层设计标准不变的情况下,可以降低轮胎生产成本。The application of a new type fiber cord EPT66(referred to as EPT66)in the cap ply of high performance passenger car tire was studied.The results showed that compared with nylon 66(referred to as N66),EPT66 had higher breaking force and adhesive force,reduced shrinkage rate and improved dimensional stability,and all properties met the requirements of enterprise standards.Using EPT66 instead of N66 as the cap ply material met the requirements of tire production standards.The indoor performance of the trial produced tires met the requirements of national standards,the safety and comfort were improved,and the service life of the tires was prolonged.Moreover,the production cost of tire could be reduced under the condition that the tire production process and cap ply design were unchanged.
