Abstract: This relates to a method, a device and a curved molded member made of composite material. From at least one composite strip (24) formed of at least two tapes (3, 4, 5) made of unidirectional reinforcing fibers, pre-impregnated with resin and pre-compacted one with the other, the strip is applied longitudinally on a silicone flexible mandrel (13), by compaction under vacuum to confer the specific shape of the mandrel to it, the resulting strip (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 pressure and temperature application mold (26), the flexible mandrel is removed then the mold is brought to pressure and temperature for polymerization, and the member is demolded after cooling.

Abstract: This method of producing a planar multi-axial composite product, comprises in particular the steps consisting of: (a) forming a mat (13) having a longitudinal direction and a transverse direction, multi-layer comprising at least the steps consisting in: laying up on a manufacturing support surface a first layer comprising juxtaposed tapes of unidirectional reinforcing fibers preimpregnated with resin, the tapes of the first layer presenting a first angle relative to the longitudinal direction of the mat, laying up on the first layer (10), at least one second layer (11, 12) comprising juxtaposed unidirectional tapes of reinforcing fibers pre-impregnated with resin, the tapes of the second layer presenting a second angle to the longitudinal direction of the mat, (b) carrying out a compaction on the at least two layers, (c) cutting the mat (13) into at least one planar multi-axial composite product having homogeneous deformability properties, in particular for double curvature, that allow members of comple

Abstract: 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.
