Title (EN) METHOD FOR MAKING COMPOSITE PARTS HAVING COMPLEX SHAPES
(FR) PROCÉDÉ DE RÉALISATION DE PIÈCES COMPOSITES DE FORME COMPLEXE
Abstract:
(EN) The invention relates to a method for making parts (6) having a complex geometrical shape, said geometrical shape including e.g. various bends, branching, deflectors, sections or thickness, that includes the steps of: forming a core part (1) having a geometry substantially similar to that of the target shape, except for the outer thickness, using a three-dimensional creation method; wrapping at least a portion of said core part with fibres previously or subsequently impregnated with resin until the final dimensions of the target shape are reached; and curing the resin.
(FR) Le procédé de réalisation de pièces (6) de forme géométrique complexe, ladite forme géométrique comprenant par exemple des coudes, ramifications, déflecteurs, sections ou épaisseurs variables, comprend des étapes : de création d'une pièce-noyau (1) de géométrie principalement similaire à la forme recherchée, sauf en ce qui concerne l'épaisseur extérieure, par un procédé de création tridimensionnelle, d'enveloppement d'au moins une partie de cette pièce-noyau par des fibres préalablement ou postérieurement imprégnées de résine, jusqu'à aboutir aux dimensions finales de la forme recherchée, de durcissement de la résine.
