摘要： The invention relates to a method and device for moulding a curved part made from composite material and to the resulting part, in which the part is made from at least one composite band (24) formed by at least two laps (3, 4, 5) of unidirectional reinforcing fibres preimpregnated with resin and pre-compacted against one another. The band is applied longitudinally to a flexible silicone mandrel (13) by means of vacuum compaction in order to confer thereon the shape of the mandrel and the resulting band (24) is deposited on a heated metal tool (31) having a curve that complements the shape of the mandrel and forming the core (32) of a temperature and pressure application mould (26). The flexible mandrel is removed, polymerisation pressure and temperature are applied to the mould and the part is removed after cooling.

摘要： The invention relates to a curved structural part (110) formed of a composite material having a fibrous reinforcement with continuous fibres and of which the cross section comprises at least two wings (10, 12), said fibres (3) extending from one wing to the other, said structural part comprising a variation in the width of its cross section (112) parallel to the local radius of curvature (203). The structural element resulting from the assembly of parts according to the invention thus has local widenings of the cross section at the connections between the parts constituting a structural element, such as an aircraft fuselage frame, and widenings at the connection with the floor profiles (120) in the case of using such a profile for the construction of an aircraft fuselage structure. The invention also relates to a method of manufacturing such a part.

摘要： 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.
