Abstract

L'invention se rapporte à un nouveau procédé qui permet d'éliminer au moins une partie d'au moins un composant métallique d'un constituant métallique (22) contenu dans un corps composite (20) à matrice céramique renforcée par des fibres, notamment en amenant au moins un renforçateur d'infiltration et/ou un précurseur de renforçateur d'infiltration et/ou une atmosphère infiltrante (50) à communiquer avec une masse perméable (30), qui entre en contact avec au moins une partie d'un corps composite, dont le composant métallique, une fois fondu, s'infiltre spontanément dans la masse perméable. Cette infiltration spontanée se produit sans qu'il soit nécessaire d'appliquer une pression ou de créer un vide.
