Zusammenfassung:	The invention relates to a method for manufacturing a rotationally symmetrical part made of composite material (100) for a propulsion assembly comprising: - manufacturing a fibre preform on a mandrel (200) having a profile corresponding to that of the component to be manufactured, and - densifying the fibre preform using a matrix. The step of manufacturing the fibre preform comprises the formation of a fibre blank (140) in the form of a strip comprising at least one layer of continuous fibres and at least one layer of discontinuous fibres, the fibre blank being formed on the mandrel, the layer of continuous fibres of the fibre blank extending at least over a complete turn around the mandrel (200). Un procédé de fabrication d'une pièce de révolution en matériau composite (100) pour ensemble propulsif comprend : - la réalisation d'une préforme fibreuse sur un mandrin (200) ayant un profil correspondant à celui de la pièce à fabriquer, et - la densification de la préforme fibreuse par une matrice. La réalisation de la préforme fibreuse comprend la formation d'une ébauche fibreuse (140) sous forme de bande comprenant au moins une couche de fibres continues et au moins une couche de fibres discontinues, l'ébauche fibreuse étant mise en forme sur le mandrin, la couche de fibres continues de l'ébauche fibreuse s'étendant au moins sur un tour complet autour du mandrin (200).
