| 中文摘要: |
| 研究同捻向结构、无外缠丝、紧密型高强度的3×0.24/9×0.225CCST钢丝帘线在全钢载重子午线轮胎胎体中的应用。结果表明：与3＋9＋15×0.175 W钢丝帘线相比，3×0.24/9×0.225CCST钢丝帘线直径和线密度较小，破断力/线密度大；采用3×0.24/9×0.225CCST钢丝帘线替代3＋9＋15×0.175W钢丝帘线用于全钢载重子午线轮胎胎体，帘布压延、裁断和成型工艺性能良好，成品轮胎的外缘尺寸变化不大，强度性能和耐久性能提高，质量减小，生产成本降低，经济效益较好。 |
| 英文摘要: |
| The application of 3×0.24/9×0.225CCST steel cord in the carcass of all-steel truck tire was presented in the study.3×0.24/9×0.225CCST compact steel cord had the twisted and laid structure at same direction，did not have outer wrapped wire，possessed high strength.Compared with 3＋9＋15×0.175W steel cord，3×0.24/9×0.225CCST steel cord had a smaller diameter and a lower linear density，and had a higher ratio of breaking force to line density.By using 3×0.24/9×0.225CCST steel cord to replace 3＋9＋15×0.175W steel cord in the carcass，the processing properties such as calendering，cutting and forming，were good，the inflated peripheral dimension of the finished tire changed little，the strength performance and endurance performance were improved，tire weight and production cost were reduced. |
