A method for producing a structural component part (1) from a fiber-reinforced plastic according to a three-dimensional winding process. Threadlike or strand-shaped fiber material (12) supplied on at least one bobbin (18) is wound around at least one filament carrier (11) in at least one winding pattern by at least one computer-controlled winding device (10). The fiber material (12) is laid down on the filament carrier (11) with a filament tensile force (F.sub.ZN) that is preadjusted by a control device (14). The filament tensile force (F.sub.Zist) is controlled depending on location and/or depending on path in order to take into account specific lay-down locations (29) on the filament carrier (11) in which a lay-down path (28) predefined by the winding pattern is departed from owing to the local geometry at preadjusted filament tensile force (F.sub.ZN).

Method for producing a casing made of a composite material for an aircraft turbine engine, the casing having an annular shape and including an annular fibrous preform formed by winding a fibrous cloth soaked in a polymer matrix, the method including the steps of: a) positioning an edge of the cloth on a molding drum, this cloth having a generally elongate shape and the edge being located at a first longitudinal end of the cloth, b) winding the cloth on the drum, over at least one rotation, so as to obtain the preform wound around the drum, c) molding of the preform and hardening of the resin which is injected into the preform or pre-impregnated on the preform, wherein the method includes, before step a), a step i) of mounting a removable stop on the drum, and in that step a) includes abutting the edge against this stop.
