摘要： The structural element for aircrafts, comprises a web (1), a foot (2) and a curved portion (3) defined between the web (1) and the foot (2), the web (1), the foot (2) and the curved portion (3) comprising at least first layers (4) with fibers defining a first orientation; and second layers (5) with fibers defining a second orientation, the first layers (4) comprising a plurality of gaps (7) at the foot (2) and/or the curved portion (3).
The method comprises stacking a plurality of first and second layers (4, 5); cutting a plurality of gaps (7) in the first layers (4) in a zone that will form the foot (2) and/or the curved portion (3); cutting a contour of the stacked first and second layers (4, 5); and shaping the stacked layers (4, 5).
