Title (EN) TUBULAR PART COMPRISING LOBES MADE FROM A COMPOSITE WITH UNIDIRECTIONAL FIBRES
(FR) PIECE TUBULAIRE A LOBES EN COMPOSITE A FIBRES UNIDIRECTIONNELLES
Abstract:
(EN) A method for manufacturing a fibrous tubular structure (11) comprising lobes (9), in which fibres (13, 15) are draped/deposited on a mandrel (19) having a shape corresponding to that of this fibrous structure (11), this draping/deposition being carried out such that at least one group of fibres (13, 15) has a same orientation with respect to the axis (A) of said fibrous structure (11), then, the fibres having been draped over an angular sector less than the total periphery of the mandrel, one of the ends of the fibrous structure is separated from the mandrel in order to allow the continuation of the draping on this same mandrel.
(FR) Procédé de fabrication d'une structure fibreuse tubulaire (11) à lobes (9), dans lequel on drape/dépose des fibres (13, 15) sur un mandrin (19) présentant une forme correspondant à celle de cette structure fibreuse (11), ce drapage/dépôt étant effectué de sorte qu'au moins un groupe de fibres (13, 15) présente une même orientation par rapport à l'axe (A) de ladite structure fibreuse (11), puis, les fibres ayant été drapées sur un secteur angulaire inférieur à la périphérie totale du mandrin, l'une des extrémités de la structure fibreuse est séparée du mandrin afin de permettre la poursuite du drapage sur ce même mandrin.
