| 摘 要： | 测试分析了超高相对分子质量聚乙烯 (UHMWPE)纤维的蠕变性能 ,研究了蠕变与温度、外加应力之间的关系。随环境温度的升高 ,纤维的恒蠕变速率增大 ,抗蠕变断裂时间变小 ,蠕变断裂伸长变大 ;随施加应力的增大 ,纤维的恒蠕变速率增大 ,抗蠕变断裂时间变小 ,蠕变断裂伸长变小。通过计算机编程拟合的蠕变曲线与实测蠕变曲线十分吻合 ,拟合出的材料相关参数与实际测量值相近。

| Abstract: | The creep deformation of ultrahigh-relative molecular weight polyethylene (UHMWPE) fiber was tested and analyzed. The relationship between creep and temperature and applied stress was studied. The constant creep rate and creep breaking elongation were increased and creep-resistance breaking time was decreased with the increase of room temperature. The constant creep rate was increased and creep-resistance breaking time and creep breaking elongation were decreased with the increase of applied stress. The fitted creep curves by programming coincided with the experimental curves. And the fitted parameters were close with the experimental data. |
