| 摘 要： | 采用Rivlin模型对EPDM／聚酰胺（PA）硫化共混物的单轴拉伸力学行为进行模拟。结果表明，2个参数的Ri。lin模型可以较好地描述PA用量不超过30份时EPDM／PA静态硫化共混物的应力-应变行为；3和5个参数的Rivlin模型在PA试验用量范围内对静态硫化共混物的拟合效果很好。3个参数的Rivlin模型可以很好地描述EP-DM／PA动态硫化共混物的应力-应变行为，但PA用量过大时，EPDM／PA动态硫化共混物显示出明显的塑料特征，拟合曲线与试验数据有所偏离。 |

| Abstract: | The uniaxial extension behaviour of vulcanized EPDM/polyamide(PA) blends was simulated with Rivlin model.The results showed that the Rivlin model with two parameters could be used to describe the stress-strain behaviour of statically vulcanized EPDM/PA blends with the addition level of PA up to 30 phr;the Rivlin models with three and five parameters gave good fit of statically vulcanized EPDM/PA blends with the addition level of PA used in the test;and the Rivlin model with three parameters could be used to describe the stress-strain behaviour of dynamically vulcanized EPDM/PA,but as the addition level of PA increased over a certain level,the dynamically vulcanized EPDM/PA blends would show the remarkable plastic characteristics and their fit curves would deviate from the test data. |
