| Abstract: | The synthesis and technology of the precursors of SiC ceramic fibers is summarized. The configurational parameters of the precursors yield,mixed elements content,molecular configuration,molecular weight and its distribution, spinnability and the mechanical properties of relevant ceramic fibers are evaluated. The direction of the precursors molecular design is how to reduce the mixed elements content of the precursors,improve its spinnability and tensile strength of the precursors fiber and increase the ceramic yield. |
