Abstract

L’invention a pour objet un procédé de conformation d’une pièce en matériau composite thermodurcissable, comprenant les étapes de : – fournir et empiler successivement : une première empreinte (4) ; un premier châssis à clous mobiles (6) ; un premier tapis chauffant (7) ; une pièce en matériau composite (8) ; un second tapis chauffant (9) ; un second châssis à clous mobiles (11) ; une seconde empreinte (12). – alimenter électriquement les tapis chauffants (7, 9) pour préchauffer la pièce (8) à une température et pendant une durée données ; – presser l’empilement à une pression prédéterminée en maintenant l’alimentation électrique des tapis chauffants (7, 9) ; – relâcher la pression de l’empilement. Figure pour l’abrégé : Figure 2The subject of the invention is a method for shaping a part made of thermosetting composite material, comprising the steps of: - supplying and stacking successively: a first cavity (4); a first movable nail frame (6); a first heating mat (7); a composite material part (8); a second heating mat (9); a second movable nail frame (11); a second cavity (12). – electrically energize the heating mats (7, 9) to preheat the part (8) to a given temperature and for a given time; – press the stack to a predetermined pressure while maintaining the power supply to the heating mats (7, 9); – release the stack pressure.
