Composite material with a glass ceramic - or ceramic matrix produced by the sol - gel - method and reinforced with fibers of the silicon carbide - type, its preparation and use

摘要

The invention relates to a matrix material vitro - a ceramic or of ceramic material obtained by the ground - gel and reinforced by fibers of sic type, characterized in that said fibers are of the type si - ti - c -. & br / & fig. 1 represents the curves of tension and compression stresses as a function of the relative deformation, for a composite material containing 24% by volume of fibers of the type si - ti - c -. & br / application to the manufacture of parts in the fields of aeronautics, space and of the motor vehicles.
