An aircraft pressurized cabin door () having an outer panel () and a door structure () including: two circumferential beams () fastened to the lateral edges of the door; a plurality of longitudinal beams () which are arranged substantially perpendicularly between the circumferential beams () and are fastened to the outer panel (), each longitudinal beam () extending from one circumferential beam () to the other. At least one longitudinal beam () is a beam that has a variable cross-section which increases from the ends (B, M) of the beam to the center (H, L) of the beam, with two bent support bars.

Aircraft pressurized cabin door with a structure formed by beams having a varying cross-section

Method and device for manufacturing a profile member of composite material, the cross-section of which has three branches, including the steps of: &#x2014;moving together two opposite edges of a panel () of sheet material in such a manner that these two opposite edges are juxtapositioned in one juxtapositioning direction; translating a pair of jaws () in a direction perpendicular to the juxta-positioning direction in such a manner that the pair of jaws () is positioned on either side of the opposite juxtapositioned edges, this translational movement of the pair of jaws () being carried out in the direction of a base (); &#x2014;simultaneously pressing the sheet material between the two jaws (), on the one hand, and between the jaws () and the base (), on the other hand; &#x2014;finishing the profile member of composite material by hardening with a matrix with which the sheet material is impregnated.
