The invention concerns a method for producing a frame comprising a section extruded according to a guide contour, said section comprising a flange and a web extending in section in directions concurrent and perpendicular to the guide contour, characterised in that it comprises the steps consisting of: a. making a fibrous preform, called a sock, having a tubular section, by means of a braiding method; b. flattening the tubular section of said sock and applying same, as a strip (200'), according to a first portion (210) of the width of said strip, onto the first face (310) of a tool (300) comprising two concurrent faces (3120, 320) whereof the intersection is parallel to the guide contour; c. folding the second portion (220) of said strip (200') onto a face (320) of the tool concurrent with the first face; d. consolidating the preform made in this way by combining same with a polymer resin. The invention also concerns a window obtained by such a method, in particular for an aircraft. |
