The invention relates to a method for manufacturing a composite aircraft window frame; the method comprises the steps of:a) positioning in a mold (3) a preform (4) made of pre-impregnated material including dispersed fibers, with a predefined orientation, in a thermosetting resin matrix;b) closing the mold (3) so as to define a gap (6) between at least one surface (7) of said preform (4) and a portion (15) of said mold (3);c) injecting thermosetting resin into the closed mold (3) through an inlet opening (11) of the mold (3) itself, so as to fill the gap (6) and completely lap said surface (7) of the preform (4); andd) applying a uniform hydrostatic pressure on the surface (7) by the injection of the resin.
