  • Carbonization of cellulosic fibrous materials in the presence of an organosilicon compound
    Patent number: 7175879
    Abstract: The subject of the present invention is a method of obtaining fibrous carbon materials by carbonization of cellulosic fibrous materials carried out continuously or batchwise in the presence of at least one organosilicon compound. Characteristically, said organosilicon compound is chosen from the family of cyclic, linear or branched polyhydrosiloxanes which are substituted with methyl and/or phenyl groups and the number-average molecular mass of which is between 250 and 10 000, advantageously between 2 500 and 5 000.
    Type: Grant
    Filed: December 5, 2000
    Date of Patent: February 13, 2007
    Assignee: Snecma Propulsion Solide
    Inventors: Pierre Olry, Sylvie Loison, Mark Kazakov, Alentin Trouchnicov
  • Method of obtaining a carbon fiber fabric by continuously carbonizing a cellulose fiber fabric
    Patent number: 6967014
    Abstract: The carbonization of cellulose fiber fabric comprises an initial stage of heat treatment up to 250° C. to 350° C., with a relatively high mean temperature rise speed of 10° C./min to 60° C./min, an intermediate stage up to 350° C. to 500° C. with a lower mean temperature rise speed of 2° C./min to 10° C./min, and a final stage up to 500° C. to 750° C. with a mean temperature rise speed that is again raised to 5° C./min to 40° C./min.
