CA 2205087
The invention relates to the field of high temperature composites made by the chemical vapor infiltration and deposition of a binding matrix within a porous structure. More particularly, the invention relates to pressure gradient processes for forcing infiltration of a reactant gas into a porous structure, apparatus for carrying out those processes, and the resulting products. The invention is particularly suited for the simultaneous CVI/CVD processing of large quantities (hundreds) of aircraft brake disks.
L'invention se rapporte au domaine des matériaux composites à haute température obtenus par infiltration et dépôt chimique en phase vapeur d'une matrice de liaison dans une structure poreuse. L'invention se rapporte plus particulièrement à des procédés à gradient de pression conçus pour forcer l'infiltration d'un gaz réactif dans une structure poreuse, à un appareil servant à réaliser ces procédés et aux produits obtenus. L'invention concerne notamment le traitement simultané par infiltration/dépôt chimique en phase vapeur de grandes quantités (centaines) de disques de freins d'avions.
