Claim:
A part manufactured from a stack of composite material fabrics which comprises at least one zone with a first sector of greater thickness than surrounding zones and a second sector disposed interior to and thicker than the first sector and a longitudinal reinforcement element situated on an edge of said zone, wherein, a) each stack of fabrics of said sectors has dimensions which form, on said edge, a ramp with a gradient having a predetermined value I/p of less than or equal to 1 to 40, so that a foot of said longitudinal reinforcing element is situated on the ramp; b) wherein the first and second sectors are stacked by first arranging the frames of the first sector, and then arranging on the fabrics of the first sector, the fabrics of the second sector such that the coinciding sector defines said edge in which the gradient of the resulting ramp is I/(p/2).
