Beschreibung
Zusammenfassung:	The invention is related to a heat treatment method for silicon and carbon-containing ceramic fibers as well as fibers of the same nature with a laminated structure and having an external carbon layer. The processing method for the invention comprises a heat treatment in vacuum, during at least three hours and at a temperature of about 1000 DEG C. This treatment yields fibers surrounded with a layer of endogenic SiO2, that is itself coated with a layer of endogenic carbon. Said fibers can be used to make composite materials with fiber reinforcement.
