摘要： Preforms for making ring-shaped parts out of a composite material may be produced by winding a strip (1) of fibrous material around an elliptical mandrel (10) to form an elliptical sleeve that may then be cut at an angle either before or after one or more densifying steps. The cutting plane is tilted relative to a straight cross-section of the elliptical sleeve, and the inner and outer portions of the cut rings are machined to form circular elements. Such elements may be used to produce ring-shaped parts made of a composite material having a reduced susceptibility to delamination when subjected to circumferential stress. The adjacent layers are needled during the winding process. A uniform needling surface density may be achieved by controllably moving the needle board (5) and the elliptical mandrel (10) relative to one another as the mandrel rotates, in order to compensate for the eccentricity of the mandrel cross-section. Such methods are particularly useful for producing brake disc preforms.

摘要： The invention relates to a method for producing a fibrous preform for the manufacture of a turbomachine blade made of composite material, the method involving using three-dimensional weaving to create a fibrous rough form (100) in a single piece with layers of longitudinal threads (c1 to c24) joined together by threads of layers of transverse threads (t1 to t24), and shaping the fibrous rough form to obtain a fibrous preform in a single piece having a part that forms the aerofoil preform and at least a part that forms a platform preform. During the course of the weaving process, the threads (c5 to c7) of a first group of longitudinal threads are led out from the fibrous rough form on the side of one of the lateral faces (110a) of the rough form to form a part (120) that corresponds to a preform of a blade platform, and threads (c3 and c4) of a second group of longitudinal threads are injected into the fibrous rough form with mutual criss-crossing between the threads of the first group and the threads of the second group. The invention also relates to a preform obtained using this method.
