Abstract (en)
[origin: WO2009115734A2] The invention relates to a method and device for producing a curved section made from composite material and to the resulting section (63), in which the section is made from at least one composite band (11) extending along a longitudinal axis. The band is formed by stacking at least two laps of unidirectional reinforcing fibres (4, 5, 6) disposed along particular orientations. The band is draped over a jig (34, 73) having an essentially elongated planar or substantially planar application face (36) with a determined configuration corresponding to that of the desired section and extending about a reference line, and the band is applied progressively and deformed simultaneously along the reference line, so that, in the part(s) having a non-zero radius of curvature, the fibres fan out progressively in the application plane.
