Método de fabricación de una estructura de material compuesto

Composite structure, comprising a laminate (1) that comprises a set of plies (11, 12, 13, ...), the laminate (1) extending between a first edge (2) and a second edge (3) and comprising:- a rising ramp (4) and a falling ramp (5), the rising ramp (4) comprising a starting point (41) and an upper point (42) and the falling ramp (5) comprising the upper point (42) and an end point (51),- plies (11, 12, 13, 14, 15, 16, ...) partially located over their preceding ply (12, 13, 14, 15, ...) and that alternatively extend from the first edge (2) or the second edge (3) and are shorter than the ply located before the preceding ply so that their ends (43, 44, 52, 53, ...) are stepped successively until they reach the top of the ramp (3, 4).
