摘要

A part (5) of composite material having a wedge(13) between two zones (11, 15), the second zone (15) being shorter than the first zone (11), whose structure comprises from its outer surface (21) to its inner surface (23): a first section (31) formed from at least two continuous sheets (41) extending parallel to its outer surface (21), the gradient of the wedge (13) being between 20% and 50%; a wedge (33) in the shape of a triangular prism with its larger surface (27) dimensioned in such a way that it forms a wedge having a gradient of less than 20%; a second section (35) formed by a plurality of continuous sheets (45) extending parallel to the surface bounded by the said first section (31) with the said wedge (33) placed upon it. The invention also relates to a process for manufacture of the part (5).
