Beschreibung
Zusammenfassung:	The invention relates to a method for manufacturing a hollow, axisymmetric part (10) which is made of composite material and extends along a longitudinal axis (X), the method comprising the following steps: a) step a: producing a tube (2) by pultruding fibres (1) with or without impregnating the fibres (1) with a polymer material; b) step b: cutting the tube (2) lengthwise into a plurality of tube portions (4); c) step c: arranging all or part of the tube portions (4) around a cylindrical mandrel (M); and d) step d: producing a filament winding (6) of fibres (7) around the mandrel (M) and the tube portions (4). Procédé de fabrication d'une pièce axisymétrique (10) creuse en matériau composite s'étendant selon un axe longitudinal (X), comportant les étapes suivantes : a) Etape a : réaliser un tube (2) par pultrusion de fibres (1) avec ou sans imprégnation des fibres (1) avec un matériau polymère, b) Etape b : découper le tube (2) dans sa longueur en une pluralité de sections de tube (4), c) Etape c : disposer tout ou partie des sections de tube (4) autour d'un mandrin (M) cylindrique, d) Etape d : réaliser un enroulement filamentaire (6) de fibres (7) autour du mandrin (M) et des sections de tube (4).
