Abstract Synthetic fiber ropes are widely used in the maritime industry, with applications from sailboat rigging to offshore platform mooring lines, thanks to their numerous qualities compared to steel cables: light weight, good specific mechanical properties and excellent marine resistance. A key feature of these ropes is their sensitivity to loading history, as this affects subsequent performance. In the present work the influence of the maximum bedding-in load level and the loading path were studied at the different rope component scales (filament, yarn and braided rope), in order to develop an optimal bedding-in procedure for braided ropes. The load levels were: 10%, 30% and 50% of the tensile break load of the sample. From the results obtained, the influence of braid construction and material have been studied, and an efficient bedding-in process has been defined. It was shown that the main parameter is the maximum load level, the loading path is not important. The load required to bed in HMPE ropes is closely related to changes in the braid angle under load.

垫料对HMPE纤维绳拉伸性能的影响

摘要 合成纤维绳索广泛应用于海事行业，从帆船索具到海上平台系泊绳索，由于与钢缆相比具有许多品质：重量轻、特定的机械性能好和优异的耐航性。这些绳索的一个关键特征是它们对加载历史的敏感性，因为这会影响后续的性能。在目前的工作中，在不同绳索组件尺度（长丝、纱线和编织绳）下研究了最大嵌入载荷水平和载荷路径的影响，以开发编织绳索的最佳嵌入程序。载荷水平为：样品拉伸断裂载荷的 10%、30% 和 50%。根据获得的结果，研究了编织结构和材料的影响，并定义了一个有效的嵌入过程。结果表明，主要参数是最大加载级别，加载路径并不重要。HMPE 绳索中所需的负载与负载下编织角的变化密切相关。
