(EN) METHOD OF MAKING A COMPOSITE ARTICLE HAVING AN INTERNAL PASSAGEWAY
(FR) PROCÉDÉ DE FABRICATION D'UN OBJET COMPOSITE COMPORTANT UN PASSAGE INTERNE
Abrégé
(EN)
In one particular embodiment, a method for making a fiber-reinforced, composite article having an internal passageway includes providing a layup tool, fiber placing a base layup onto the layup tool, and generating a groove in the base layup. The method further includes placing a mandrel in the groove, fiber placing a top layup onto the base layup and the mandrel, curing the base layup and the top layup, and removing the mandrel from the base layup and the top layup. In another particular embodiment, the mandrel is replaced with a non-removable tube.

Selon un mode de réalisation particulier, un procédé de fabrication d'un objet composite renforcé de fibres comportant un passage interne comprend les étapes consistant à utiliser un outil de superposition, à placer sous forme de fibres une superposition de base sur l'outil de superposition, et à produire une rainure dans la superposition de base. Le procédé comprend en outre les étapes consistant à placer un mandrin dans la rainure, à placer sous forme de fibres une superposition supérieure sur la superposition de base et le mandrin, à durcir la superposition de base et la superposition supérieure, et à retirer le mandrin de la superposition de base et de la superposition supérieure. Selon un autre mode de réalisation particulier, le mandrin est remplacé par un tube non amovible.
