Composite material part (11) with stringer (31) on ramp, manufactured from a stack of fabrics, which comprises at least one zone (13) with two sectors (17, 19) having a greater thickness than that of the surrounding zones and with the stringer (31) situated on an edge (21) of said zone (13) in which: a) each group of fabrics (27, 27′ . . . ; 29, 29′, . . . ) of said sectors (17, 19) has the dimensions to form on said edge (21) a ramp with an acceptable gradient 1/p so that the stringer (31) remains situated on the ramp; b) the stacking of the zone (13) is carried out firstly by placing the fabrics (27, 27′, . . . ) of the first sector (17) and on these the fabrics (29, 29′, . . . ) of the second sector (19) in such a way that in the coinciding section (35) of said edge (21) the gradient of the resulting ramp is 1/(p/2).
A part (11) manufactured from a stack of composite material fabrics which comprises at least one zone (13) with a first sector (17) of greater thickness than the surrounding zones and a second sector (19) interior to and thicker than the first sector (17), with a longitudinal reinforcement element (31) situated on the edge (21) of said zone (13) characterised in that:
