Development of polymer-derived SiC fiber

Abstract

The polymer - derived SiC fiber is one of the most important reinforcing materials for high performance ceramic matrix composites (CMC). Three generations of SiC fibers have been developed over the past thirty years. In this article, the preparing methods, compositions, microstructures and performances of three generation fibers are reviewed. Furthermore, the relationships are discussed between microstructure and the main properties of the fibers, such as high temperature-resistance and creep resistance. as a summary, some improving methods for the properties of SiC fibers derived from precursor are summarized.
