| 中文摘要: |
| 研究3×0.24/9×0.225CCST钢丝帘线的性能及其在全钢载重子午线轮胎胎体中的应用效果。结果表明：与0.22＋6＋12×0.20HT钢丝帘线相比，3×0.24/9×0.225CCST钢丝帘线的直径和线密度减小，单位直径和线密度的破断力增大，渗胶性能提高，工艺性能优良；与0.22＋6＋12×0.20HT钢丝帘线成品轮胎相比，3×0.24/9×0.225CCST钢丝帘线成品轮胎强度、耐久性能和胎圈耐久性能提高，同时可减小轮胎质量，降低制造成本。 |
| 英文摘要: |
| The properties of 3×0.24/9×0.225CCST steel cord and its application effect in the carcass of truck and bus radial tire were investigated.The results showed that，compared with 0.22＋6＋12×0.20HT steel cord，the diameter and linear density of 3×0.24/9×0.225CCST steel cord were decreased，the unit diameter and unit linear density breaking force were increased，the compound permeability was improved and the processing performance were good.The strength，durability and bead durability of the finished tire adopted 3×0.24/9×0.225CCST steel cord were improved compared with those of the finished tire adopted 0.22＋6＋12×0.20HT steel cord，meanwhile the weight and manufacturing cost of the tire were reduced. |
