Title (EN) PROCESS FOR PRODUCING PREFORMS WITH APPLICATION OF A BINDER TO DRY FIBRE FORMED FROM A PLURALITY OF INITIAL FIBRES
(FR) PROCÉDÉ DE RÉALISATION DE PRÉFORMÉS AVEC APPLICATION D'UN LIANT SUR FIBRE SÈCHE FORMÉE DE PLUSIEURS FIBRES INITIALES
Abstract:
(EN) The invention relates to a process for producing preforms, comprising the application of a binder to a continuous dry fibre (9) formed from at least two initial fibres, and the layup of said fibre using a layup head in order to form a preform. Binder is applied by means of a fiberisation nozzle (50) comprising a discharge orifice (53) supplied with liquid or pasty binder, and one or more injection orifices (57) supplied with pressurised gas, so as to deliver the binder in the form of a spiral strand (92), the coils being deposited on the fibre running past a nozzle in order to obtain a fibre provided with strands (93) of binder, said strands bonding the initial fibres together.
(FR) L'invention concerne un procédé de réalisation de préformes comprenant l'application d'un liant sur une fibre (9) sèche continue formée à partir d'au moins deux fibres initiales, et le drapage de ladite fibre au moyen d'une tête de drapage pour former une préforme. L'application de liant est réalisée au moyen d'une buse de fibérisation (50) comprenant un orifice de décharge (53) alimenté en liant liquide ou pâteux, et un ou plusieurs orifices d'injection (57) alimentés en gaz sous pression, de façon à délivrer le liant sous la forme d'un filament en spirale (92), les spires se déposant sur la fibre défilant en vis-à-vis d'une buse pour obtenir une fibre munie de filaments (93) de liant, lesdits filaments assurant une liaison entre les fibres initiales.
