1×3×0.28HT钢丝帘线在轿车子午线轮胎中的应用

Application of 1×3×0.28HT steel cord in PCR tire

试验研究1×3×0.28HT钢丝帘线在轿车子午线轮胎带束层中的应用情况。结果表明,在轿车子午线轮胎带束层中以1×3×0.28HT钢丝帘线替代1×4×0.25钢丝帘线可以提高轮胎的高速性能和安全倍数,其它性能不受影响,而且有望实现轮胎的轻量化,降低成本。

Abstract：The application of 1× 3 ×0.28HT steel cord in the belt of PCR tire was experimentally investigated. The results showed that the high speed performance and safety factor improved by using 1×3×0.28HT steel cord in the belt of PCR tire instead of 1 ×4×0.25 steel cord without any adverse effect on other properties,in addition,the weight and cost of tire could be reduced.
