| 中文摘要: |
| 测定了子午线轮胎复合材料（胎体帘布层、锦纶带束层、钢丝带束层和冠带层）中的杨氏模量、泊松比和密度，并通过对所得数据进行理论分析得知，复合材料的力学性质介于线性和非线性之间，在小变形范围内，钢丝和纤维帘线是线性的，而橡胶则呈现明显的非线性；在大变形范围内，胎体帘布层、锦纶带束层、钢丝带束层和冠带层等复合材料均呈现非线性。 |
| 英文摘要: |
| The Youngs modulus，Poissons ratio and density of radial tire composites，such as carcass ply，nylon belt，steel belt and crown ply were determined.It was found through the analysis of the obtained data that the mechanical characteristics of composites was between linearity and non-linearity，i.e.that of steel cord or textile cord was linear and that of rubber was non-linear in the small deformation，and the mechanical
characteristics of all the composites was non-linear in large deformation. |
