Process for manufacturing an assembly made of a composite material and wing and stabilizing element obtained by this process. The junction zone for a part (P) made of a composite material comprising two parts (A1, A2) in which the principal directions intersect at a non- singular angle, is made in a single operation by continuous lay-up. The 0° directions of the lay-up coordinate systems (R1, R2) of the parts (A1, A2) are oriented such that these directions make an angle of close to 180°- .theta.°, where +.theta.° represents the other directions of the lay-up coordinate systems (R1, R2). Thus, the layers of fibers oriented at 0° in one of the coordinate systems correspond approximately to a lay-up direction of +.theta.° in the other coordinate system.
Procédé de fabrication d'un ensemble en matériau composite ainsi que voilure et élément stabilisateur obtenus grâce à ce procédé. La zone de jonction d'une pièce (P) en matériau composite, comportant deux parties (A1, A2) dont les principales se coupent selon un angle non singulier, est fabriquée en une seule opération, par drapage en continu. € cet effet, on oriente les directions zéro degré des repères de drapage (R1, R2) des parties (A1, A2) de telle sorte que ces directions fassent entre elles un angle voisin de 180 degrés moins thêta degré, plus ou moins thêta degré représentant d'autres directions des repères de drapage (R1, R2). Ainsi, les nappes de fibres orientées à zéro degré dans l'un des repères correspondent sensiblement à une direction de drapage de plus ou moins thêta degré dans l'autre repère.
