Method of forming a fibrous structure composite ceramic material and material thus obtained

摘要

A method is provided for forming a composite ceramic material, in which a fibrous structure is first of all formed which is then embedded in the material of a ceramic matrix. To introduce said matrix into said structure, the following succession of operations is carried out: (a) said fibrous support is impregnated with a polymerization catalyst for an organometallic precursor of said ceramic matrix; (b) said fibrous support impregnated with said polymerization catalyst is placed in contact with said organometallic precursor; (c) said organometallic precursor is polymerized, and (d) said organometallic precursor is pyrolysed so as to obtain said matrix.
