采用多种分析手段对国内某公司生产的玄武岩纤维纱线的高温性能及其机理进行研究。结果表明，随温度的升高，玄武岩纤维纱线的断裂强度呈现先增加后降低的规律，其中，在200℃时能够获得最佳力学性能。在升温过程中，表面处理剂先后发生团聚、分解挥发等变化，主要通过改变纱线的表面粗糙度和承受载荷的纤维数目间接地影响断裂强度。此外，高温处理后的玄武岩纤维纱线内部结构受到一定程度的不可逆破坏。

The high temperature resistance and its mechanism were carried out on the basalt fiber yarn produced from a domestic company by a variety of analysis methods.The results show that fracture strength of basalt fi-ber yarn has a special law of decrease after a first decrease with the increasing of temperature,while,it can ob-tain the best mechanical properties at 200 ℃.During the process of heating up,the surface treating agent would have an experience of reunion and decomposition successively,which has an indirect influence on fracture strength by changing surface roughness and the number of loaded fiber of fiber yarn.What’s more,the internal structure of basalt fiber yarn was destroyed at some extent after treated at high temperature.
