A method of manufacturing a structure, in particular an aircraft fuselage of composite materials comprising a skin (2) and V-section members fastened to the skin (2) referred to as stiffeners (4). The method comprises a step of positioning punches on a mandrel in order to form channels between the punches. The channels are disposed in at least two networks (6a, 6b, 6c), each channel of the same network (6a, 6b, 6c) meeting at least one channel of another network at a node (8). The method also comprises a step of positioning preforms for stiffeners in the channels such that at least two stiffeners (4) meet at said node (8) and a step of injecting resin so as to assemble the stiffeners (4). A structure made as a single piece is thereby obtained.
