MANUFACTURE OF COMPOSITE MATERIAL CONSISTING OF GLASS CERAMIC OR CERAMIC MATRIX BY USING SOL-GEL PROCESS, AND COMPOSITE MATERIAL THUS OBTAINED |
摘要 |
Process for the manufacture, by a sol-gel route and compression with heating, of a composite material consisting of a fibrous reinforcement and of a vitro-ceramic or ceramic matrix based on silica. …<??>The process of the invention is characterised in that the premature crystallisation of the matrix originating from the sol is delayed by the addition of a crystallisation-retarding agent to the sol. …<??>This process makes it possible to obtain well-densified composite materials which have a residual porosity of less than 10%, this being done without adding new nucleating agents. |
