Method for manufacturing a composite material part comprising a web and at least one flange

摘要

A method for manufacturing a composite material part comprising a web and at least one flange. In a laying up stage, a plurality of plies of different orientations, including 0° oriented plies, are laid up to obtain a flat laminate with edges comprising an outer contour and an inner contour, the flat laminate also comprising at least one section with a radius of curvature of less than 10 m. A forming stage comprises forming a fold along a folding line on the flat laminate to create a flange forming an angle with the web, and applying a stress tension to the 0° oriented plies located at least partially between the folding line and the outer contour of the flat laminate, in the at least one section, to avoid the appearance of wrinkles.

1. A method for manufacturing a composite material part comprising a web and at least one flange comprising the following stages:
a laying up stage which comprises a step of laying up a plurality of plies of different orientations, including 0° oriented plies, to obtain a flat laminate with edges comprising an outer contour and an inner contour, the flat laminate also comprising at least one section with a radius of curvature of less than 10 m, and a forming stage which comprises forming a fold along a folding line on the flat laminate to create a flange forming an angle with the web, the forming stage additionally comprising a step of applying a stress tension to the 0° oriented plies located at least partially between the folding line and the outer contour of the flat laminate in the at least one section with a radius of curvature of less than 10 m to avoid the appearance of wrinkles, wherein the 0° oriented plies located at least partially between the folding line and the outer contour of the flat laminate in the at least one section with a radius of curvature of less than 10 m extend laterally on both sides beyond the edges of the flat laminate.
