  • Method for producing silicon oxycarbide fibers
    Patent number: 7371340
    Abstract: The present invention relates to a method for producing silicon oxycarbide fibers by pyrolysis of preceramic precursors. Said method comprises the following steps: spinning of a composition comprising a silicone polymer and a reticulating agent, chemical reticulation of the fibers and pyrolysis at a temperature between 800 and 1400° C. in non-oxidizing atmosphere. Said method is characterized by the use of a polyorganohydrosiloxane as silicone polymer and by a reticulating agent that carries out reticulation by reacting with Si—H bonds of polyorganohydrosiloxane.
