Abstract

Outillage (110) pour la fabrication d’une pièce aéronautique en matériau composite, cet outillage comportant une cavité (116) configurée pour recevoir une préforme fibreuse comportant des fibres enrobées avec une résine polymérisable, caractérisé en ce que l’outillage comprend en outre au moins un élément (122) de forme allongée en silicone qui est logé dans une rainure (124) débouchant dans la cavité, le long d’un bord périphérique de cette dernière, ledit élément étant configuré pour avoir à température ambiante un premier volume tel que l’élément est entièrement logé dans la rainure, et pour avoir à une température K prédéterminée un second volume tel que l’élément est au moins en partie en saillie à l’extérieur de la rainure et à l’intérieur de la cavité et prend appui sur la préforme en vue d’exercer sur un bord de celle-ci une pression d’essorage. Figure pour l'abrégé : Figure 2Tooling (110) for the manufacture of an aeronautical part made of composite material, this tooling comprising a cavity (116) configured to receive a fiber preform comprising fibers coated with a polymerizable resin, characterized in that the tooling further comprises at at least one element (122) of elongated shape made of silicone which is housed in a groove (124) opening into the cavity, along a peripheral edge of the latter, said element being configured to have at room temperature a first volume such that the element is completely housed in the groove, and to have at a predetermined temperature K a second volume such that the element is at least partly projecting outside the groove and inside the cavity and takes pressing on the preform in order to exert a wiping pressure on one edge of the latter.
