| 中文摘要: |
| 介绍3+8×0.33ST超高强钢丝帘线在载重子午线轮胎带束层中的应用。结果表明：与3+9+15×0.22+015NT钢丝帘线相比，3+8×0.33ST超高强钢丝帘线的H抽出力增大10.1%，将其应用于4层带束结构载重子午线轮胎带束工作层，轮胎成本降低4.6%，同时还可以大幅减少轮胎冠空爆发生率。 |
| 英文摘要: |
| The application of 3+8×0.33ST ultra high strength steel cord in the belt of truck and bus radial (TBR) tire was investigated.The results showed that，compared with 3+9+15×0.22+0.15NT steel cord，the H pull out force of 3+8×0.33ST ultra high strength steel cord was higher by 10.1%.With 3+8×0.33ST steel cord in main belt layer of the TBR tire which had 4 layers of belt，the tire cost was reduced by 4.6%，and the delamination and cracking of tire crown were effectively prevented. |
