中文摘要:
      介绍新开发的0.23＋18×0.21CCST钢丝帘线的性能，并与0.17＋5×0.215＋10×0.235CCST钢丝帘线进行对比。0.23＋18×0.21CCST钢丝帘线由19根超高强度单丝组成，以相同捻向和捻距一次编捻而成，截面为正六边形；与0.17＋5×0.215＋10×0.235CCST钢丝帘线相比，其线密度和H抽出力较大，弯曲刚度较小，弹性模量和冲击功较高，耐疲劳性能更好。0.23＋18×0.21CCST钢丝帘线适用于无内胎全钢载重子午线轮胎胎体，有利于提高轮胎的耐疲劳性能、延长使用寿命。
英文摘要:
      The properties of the newly developed 0.23＋18×0.21CCST steel cord was introduced and compared with the 0.17＋5×0.215＋10×0.235CCST steel cord.The 0.23＋18×0.21CCST steel cord was composed of 19 super-high tenacity monofilaments，which were knitted and twisted at one time with the same twist direction and pitch，its cross-section was a regular hexagon.Compared with 0.17＋5×0.215＋10×0.235CCST steel cord，it possessed bigger linear density and H pull-out force，smaller bending stiffness，higher elastic modulus and impact energy，better fatigue resistance.0.23＋18×0.21CCST steel cord was suitable for the carcass of tubeless truck and bus radial tire，which was beneficial to improve the fatigue resistance of the tire and prolong the service life.
