  • Heat treatment method for silicon and carbon-containing ceramic fibers and fibers of the same kind with a laminated structure
    Patent number: 5240887
    Abstract: 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.degree. C. This treatment yields fibers surrounded with a layer of endogenic SiO.sub.2, that is itself coated with a layer of endogenic carbon.Said fibers can be used to make composite materials with fiber reinforcement.

  • Method of manufacturing a composite material with vitroceramic or ceramic matrix using a sol-gel process
    Patent number: 5126087
    Abstract: A method of manufacturing a composite material formed of a fibrous reinforcement and a silica based ceramic or vitro-ceramic matrix. The method includes impregnating the fibrous reinforcement by means of a sol-gel process wherein premature crystallization of the matrix obtained from the sol is hindered by addition to the sol of a crystallization retarding agent, and hot pressing the resulting material. The composite material formed has a residual porosity without the addition of nucleating agents of about less than 10%.
