Title (EN) METHOD FOR PRODUCING THREE DIMENSIONAL PREFORMS BY FORMING INITIAL TENSIONED PREFORMS
(FR) PROCÉDÉ DE RÉALISATION DE PRÉFORMES TRIDIMENSIONNELLES PAR FORMAGE DE PRÉFORMES INITIALES MISES SOUS TENSION
Abstract:
(EN) A method for producing a three-dimensional preform, consisting in producing an initial preform (4) and forming the initial preform between the male forming tool and the female forming tool of a press to obtain a three-dimensional preform. The initial preform is obtained by producing stacked plies by the contact-application, via an application roller, of unidirectional continuous fibres on a draping tool (2), wherein one or more plies comprise fibres having extensions (61a, 61b, 62a, 62b, 71a, 71b, 72a, 72b), said extensions constituting gripping portions. Said gripping portions are placed in gripping means of a tensioning system such that they selectively apply tensioning to said fibres during the forming operation.
(FR) Un procédé de réalisation ' d'une préforme tridimensionnelle comprenant la réalisation d'une préfôrme initiale (4), et le formage de la préforme initiale entre l'outillage de formage mâle et l'outillage de formage femelle d'une presse pour obtenir une préforme tridimensionnelle. La réalisation de la préforme initiale comprend la réalisation de plis superposés par application au contact, au moyen d'un rouleau d'application, de fibres continues unidirectionnelles sur un outillage de drapage (2), un ou plusieurs plis comprenant des fibres qui présentent des extensions (61a, 61b, 62â, 62b, 71a, 71b, 72a, 72b), lesdites extensions constituant des portions de serrage. Lesdites portions de serrage sont placées dans des moyens de serrage d'un système de tension de manière à appliquer de manière, sélective de la tension dans lesdites fibres lors de l'opération de, formage.
