摘　　要：回顾了绳缆发展的4个阶段以及材料强度不断提高的过程,介绍了材料的理论极限强度,并以超高相对分子质量聚乙烯纤维为例,通过对其微观组织结构以及在拉力下的变形过程和微观失效机理的分析,讨论了材料实际强度远低于理论极限强度的原因,指出绳缆材料的实际强度只有理论极限强度的大约10%,其原因是材料尺寸增大时微观结构中就会产生缺陷和薄弱环节。最后展望了制绳纤维材料的未来发展趋势。This paper starts with a review of the history of rope development and the four generations of ropes, of which strength has been increased continuously. The theoretical ultimate strength of materials is then introduced and the reasons why actual strength is well below theoretical values are analysed by taking UHMWPE as an example and discussing the microstructures, deformation characteristics and failure mechanisms. The last section of the paper provides an outlook of the prospects of future developmentof rope making fibres.
