Abstract
Organopolysilanes and -carbosilanes are already used as starting materials for the commercial production of SiC-based fibers. The process, originally derived from the method described by Yajima involves the melt-, wet- or dry- spinning of organosilicon polymers followed by a curing step and subsequent pyrolysis of the polymer fiber providing the ceramic fiber [1,2]. The intermediate curing step results in an increased cross-linking of the polymer and hence in the formation of an infusible polymer fiber necessary for the shape retaining thermal conversion into the ceramic material.
