PROCESS FOR MANUFACTURING A THERMOSTRUCTURAL COMPOSITE PART |
摘要 |
<p>The invention relates to a process for manufacturing a part made of a composite comprising a fibrous reinforcement densified by a matrix, which process comprises the steps of: production of a fibrous preform consolidated by impregnation (S4) of a fibrous texture comprising yarns by means of a liquid consolidation composition containing a precursor of a consolidating material and transformation (S7) by pyrolysis of the precursor made of consolidating material so as to obtain a consolidated preform of maintained shape; and densification (S8) of the consolidated fibrous preform by chemical vapour infiltration, characterized in that it includes, before the impregnation (S4) of the fibrous texture with the liquid consolidation composition, a step (S2) of filling the porosity of the yarns of said texture by means of a filling composition.</p> |
