Title (EN) METHOD FOR PRODUCING A COMPOSITE MATERIAL PART BY THE ORIENTED NEEDLING OF A PREFORM
(FR) PROCÉDÉ DE RÉALISATION D'UNE PIÈCE EN MATÉRIAU COMPOSITE PAR AIGUILLETAGE ORIENTÉ D'UNE PRÉFORME
Abstract:
(EN) The present invention relates to a method for producing a composite material part comprising - a step of producing a preform formed of unidirectional continuous fibres oriented in at least one fibre orientation, - a step of applying non-woven filaments to the preform, and - a step of needling the filaments by means of a needling device comprising a plurality of needles, each needle being provided with a notch (82) extending along a notch axis (B) perpendicular to the main longitudinal axis of the needle, or several notches each extending along a notch axis perpendicular to the main longitudinal axis of the needle, said notch axes being parallel to each other, said needles and the preform being arranged so that the notch axes form a non-zero angle with the fibre orientation.
(FR) La présente invention concerne un procédé de réalisation d'une pièce en matériau composite comprenant - une étape de réalisation d'une préforme formée fibres continues unidirectionnelles orientées selon au moins une orientation de fibre, - une étape d'application de filaments non tissés sur la préforme, et - une étape d'aiguilletage desdits filaments au moyen d'un dispositif d'aiguilletage comprenant une pluralité d'aiguilles, chaque aiguille étant munie d'une encoche (82) s'étendant selon un axe (B) d'encoche perpendiculaire à l'axe principal longitudinal de l'aiguille, ou de plusieurs encoches s'étendant chacune selon un axe d'encoche perpendiculaire à l'axe principal longitudinal de l'aiguille, lesdits axes d'encoche étant parallèles entre eux, lesdites aiguilles et la préforme étant disposées de sorte que les axes d'encoche forment un angle non nul avec l'orientation de fibre.
