| 摘要 |
The invention relates to a method for producing a planar multi-axial composite product, including the following steps: (a) forming a multi-layer mat (13) having a longitudinal direction and a transverse direction, said step including at least a step in which a first layer comprising juxtaposed, resin-preimpregnated, unidirectional laps of reinforcing fibres is draped over a production supporting surface, said first layer laps forming a first angle in relation to the longitudinal direction of the mat, and a step in which at least a second layer (11, 12) comprising juxtaposed, resin-preimpregnated, unidirectional laps of reinforcing fibres is draped over the first layer (10), said second layer laps forming a second angle in relation to the longitudinal direction of the mat; (b) compacting the at least two layers, and (c) cutting the mat (13) into at least one planar multi-axial composite product having homogeneous deformation properties, particularly in terms of double curvature, enabling the production of parts with complex shapes. |
