摘　　要：比较了连续ＳｉＣ纤维的四种主要制备方法，着重介绍了先驱体转化法制备工艺，并就先驱体转化法生产连续ＳｉＣ纤维国内外研究历程、开发现状、发展前景及对策作了初步的分析与探讨．To prepare continuous silicon carbide fibers, four methods were reviewed, of which polymer route is taking its predominace these days. The polymer route to ceramic fibers, usually containing steps of polymer synthesis, melt spinning, curing and pyrolysis, was thoroughly studied. The development of the fibers was discussed and new generation fibers for ultrahigh-temperature applications, which is the main advance in this field, were remarked by Hi-Nicalon, Hi-Nicalon type S, Sylramic, Tyranno SA and Siboramic. Current situation of the polymer-derived continuous SiC fibers at home and abroad, as well as their prospects and countermeasures, were also discussed in the paper.
