Method and device for producing a curved profile made from composite material and resulting profile

A device (30, 70) for realizing a composite material profile having a configuration with at least a first part having a non-zero curvature radius, from at least one composite strip (11) extending along a longitudinal axis (15), characterized in that the strip being formed of at least two tapes (1, 2, 3) of unidirectional reinforcing fibers arranged according to orientations different to that of the longitudinal axis of the strip and each other, the tapes being pre-impregnated with resin and pre-compacted with one another at a specified pressure and temperature,

• the device comprises
• at least one composite strip (11) support base (31),
• a template (34) having a flat or substantially flat application surface (36) with a generally elongated shape, with a specified configuration corresponding to the desired profile and extending around a reference line,
• means (37) for gradually laying up the strip on the template comprising
• means (38) for gripping the base and of moving said base along said template,
• means (44) for pressing the tape by the base on the template's application surface,
• means (43) for guiding said base to cause a laying up of the strip on the application surface along the said reference line, such that a gradual fanning of the fibers in the application plane is realized on the part or parts having a non-zero curvature radius.
