Abstract: 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 dicussed in the paper.

Key words: polymer pyrolysis, continuous silicon carbide fibers, development, current situation
