Method for manufacturing a composite material part (1) comprising a web (2) and at least one flange (3) comprising the following stages:
- a laying up stage, wherein a plurality of plies (9) of different orientations, including 0º oriented plies, are laid up to obtain a flat laminate (4) with edges comprising an outer contour (6) and an inner contour (7), the flat laminate (4) also comprising at least one section (11) with a radius of curvature of less than 10 m, and
- a forming stage which comprises forming a fold (8) along a folding line (5) on the flat laminate (4) to create a flange (3) forming an angle with the web (2),
the forming stage additionally comprising applying a stress tension to the 0º oriented plies located at least partially between the folding line (5) and the outer contour (6) of the flat laminate (4) in the at least one section (11) to avoid the appearance of wrinkles. |
