COMPOSITE MATERIAL WITH VITRO-CERAMIC OR CERAMIC MATRIX OBTAINED BY THE SOL-GEL PATH AND REINFORCED WITH SICILIUM CARBIDE-TYPE FIBERS, ITS MANUFACTURE AND ITS APPLICATIONS

摘要

The subject of the invention is a material with a ceramic-ceramic or ceramic matrix obtained by the sol-gel route and reinforced with SiC-type fibers, characterized in that the said fibers are of the Si-Ti-C-O type. BR/ The figure represents the stress curves in compression and tension, as a function of the relative strain, for a composite material containing 24% by volume of Si-Ti-C-O type fibers. BR/ Application to the manufacture of parts in the fields of aeronautics, space and automotive engines. / P
