摘　　要：针对采用玄武岩纤维编织绳索过程中出现的力学损伤问题,采用16锭编织机制备玄武岩纤维绳索,探究编织参数对玄武岩纤维绳索力学性能的影响,分析断头和接头方式对玄武岩纤维绳索强力的影响。结果表明在玄武岩复丝二维编织过程中,编织速度是影响绳索断裂强力和断裂伸长率的重要因素,复丝间张力不匀会使复丝内部纤维形成摩擦效应,导致绳索表观结构恶化,力学性能损伤严重。玄武岩纤维编织过程中复丝断裂后可进行停机接头再编织,既方便连续生产,又能确保其整体力学性能几乎无损失。In response to the mechanical damage problems that occurred during the preparation of basalt ropes,16 spindles braiding machine was used to prepare basalt fiber rope,and the influence of braiding parameters on the mechanical properties of basalt fiber rope were explored,the effect of broken and joint mode on the strength of basalt fiber rope were analyzed.The results showed that the braiding speed was an important factor which could affect the strength and elongation of the basalt fiber rope during the two-dimentional braiding process.The friction effect caused by the uneven tension among the multi-filaments would lead to the deterioration of the apparent structure and serious mechanical damage.In the braiding process of basalt fiber rope,the broken multi-filament could be re-braided to the stop joint,which was not only convenient for continuous production,but also could ensure almost no loss of mechanical properties of the basalt fiber rope.
