| 中文摘要: |
| 研究锦纶66帘布和混纺芳纶帘布（锦纶66＋芳纶纤维）作为冠带层材料对子午线轮胎性能的影响。结果表明，与冠带层采用锦纶66帘布的轮胎相比，冠带层采用混纺芳纶帘布的轮胎的接地印痕矩形率增大，高速性能和侧偏特性更优，且在耐久性能测试后充气外直径变化量小。 |
| 英文摘要: |
| The effects of nylon 66 cord fabric and blended aramid cord（nylon 66＋aramid fiber） as the cap ply materials on the performance of radial tires was studied.The results showed that，compared with tires using nylon 66 cord fabric in the cap ply，tires with blended aramid cord fabric in the cap ply exhibited an increased rectangularity ratio of the footprint，better high speed performance and cornering characteristics，and a smaller change in inflated overrall diameter before and after durability testing. |
