摘要： 继刚性聚合物经溶液液晶(如芳香族聚酰胺)或熔融液晶(如芳香族聚酯)纺丝制取高性能纤维获得成功后,利用冻胶纺丝等技术制取超高分子量聚乙烯(UHMW-PE)高性能纤维的研究已取得突破性进展。这类纤维具有伸直链结构,大分子沿材料拉伸方向高度取向和结晶,显示出优异的抗张性能,具有很大的拉伸强度和模量。

关键词: 超高分子量聚乙烯膜, 轴向压缩, 晶面滑移

Abstract: The axial compressional behavior of ultra-high molecular weight polyethylene (UHMW-PE) film is studied by means of polarizing optical microscopy, scanning electron microscopy and X-ray diffraction in this paper. The results show that a lot of kink bands are formed at about 75° and 90°. It is suggested that (110)〈001〉 and (100)〈001〉crystallo-graphic slips play the dominant role in the formation of the 75° kink bands and 90° kink bands.

Key words: Ultra-high molecular weight polyethylene film, Axial compression, Crystallo-graphic slip
