Abstract

La présente invention concerne une structure composite métal-céramique présentant une cavité ou toute autre structure creuse à l'intérieur. La cavité n'est ni découpée, ni usinée dans la structure finale, mais elle est formée au cours du processus d'infiltration. Dans le système présentant des matériaux composites Si/SiC en particulier, une préforme est utilisée, laquelle présente ladite cavité souhaitée, ou encore, plusieurs préformes de sous-unités sont reliées ensemble de manière à former ou à définir ladite cavité. Un matériau essentiellement impénétrable par le matériau infiltrant fondu est mis en contact avec la quasi totalité des surfaces intérieures, par exemple, les parois, de la cavité. La mise en contact peut consister essentiellement en un enrobage des parois, ou elle peut consister en un remplissage substantiel de la cavité avec le matériau impénétrable, ou un matériau similaire. De préférence, le matériau impénétrable se présente sous une forme permettant un retrait rapide après le traitement, telle qu'une masse de matière particulaire collée de manière lâche. La préforme ou l'assemblage de sous-unités peuvent ensuite être imprégnés normalement par le matériau infiltrant fondu. Le matériau infiltrant ne s'infiltre pas dans la cavité, il est localement stoppé par le matériau impénétrable sur les parois de la cavité. Après solidification du matériau infiltrant pour former un corps RBSC, le matériau impénétrable est rapidement retiré, par exemple, par jets d'air ou d'eau, par agitation, application d'un vide d'air, etc. En outre, un ou plusieurs orifices d'accès provisoires à la cavité peuvent être usinés dans la structure composite, par exemple, pour permettre un accès supplémentaire à un moyen à jet de pression ou à un moyen de vide; ces orifices d'accès sont rebouchés après retrait du matériau impénétrable.
