METHOD AND DEVICE FOR PRODUCING A CURVED SECTION MADE FROM COMPOSITE MATERIAL AND RESULTING SECTION

A method and a device for realizing a curved composite material profile made of composite material, and to the resulting profile (63), in which the profile is made from at least one composite strip (11) extending along a longitudinal axis. The strip is formed by stacking at least two tapes of unidir...

Zusammenfassung:	A method and a device for realizing a curved composite material profile made of composite material, and to the resulting profile (63), in which the profile is made from at least one composite strip (11) extending along a longitudinal axis. The strip is formed by stacking at least two tapes of unidirectional reinforcing fibers (4, 5, 6) arranged in orientations. The strip is laid up on a template (34, 73) 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, by gradually applying the strip and simultaneously deforming it along the 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
