| 摘 要： | 超高分子量聚乙烯(UHMWPE)的初生凝胶电丝在超倍拉伸(简称为超拉伸)过程中其结构和性能要发生一系列变化。描述和表征这一过程可采用多种途径和多项指标。本文在用传统表征方法相比较的基础上提出了可用小角 X 射线散射(SAXS)强度来衡量纤维中的缺陷度,而缺陷度能很好地表征纤维在整个拉伸过程中力学性能的变化规律。本文的结论同时亦适用于其它高性能纤维品种,如 PVA 凝胶纤维等。 |

| Abstract: | Structures and properties of as-spun ultra-high molecular weight polyethylene(UHMWPE)gel fibers change in ultra-drawing process.Classical ways and parameters,suchas draw ratios,crystallinity and orientation functions cannot well explain the changes andhigh performances of drawn,especially ultra-drawn fibers,which are investigated by SAXSin this paper.To indicate the degree of flaws and defects,the SAXS intensity can be used as astructure parameter of drawn fibers,it is more effective than the classical ways. |
| Keywords: | polyethylene fiber drawing gel small angle scattering flaws gel-spinning small angle X-ray scattering ultra-drawing ultra-high molecular weight polyethylene degree of flaws and defects |
