A fibrous preform (10) of the component to be manufactured is conformed in the desired shape with the desired degree of compacting, prior to densification by chemical vapor deposition. According to the invention, the conformation is achieved by linking the preform (10) onto a rigid shaping device (12) by means of threads (30) that traverse the preform (10) and pass through holes (14) in the shaping device. The linking threads (30) are made of carbon or ceramic. Prior to the linking, a covering layer (16) may be arranged on the face of the preform (10) opposite to the one turned towards the shaping device.
La préforme fibreuse (10) du composant à fabriquer est conformée, à la forme voulue, au degré voulu de compactage, avant la densification par dépôt chimique en phase vapeur. Grâce à l'invention, la conformation est obtenue en connectant la préforme (10) à un dispositif rigide de formage (12) au moyen de filets (30) qui traversent la préforme (10) et passent dans des trous (14) dans le dispositif de formage. Les filets de connexion (30) sont faits de carbone ou de céramique. Avant la connexion, une couche de recouvrement (16) peut être mise sur la face de la préforme (10) à l'opposé de celle qui est tournée vers le dispositif de formage.
