A method for producing a part made of a composite material having an organic matrix and a fibrous reinforcement, the method comprising the following steps: a) automatically draping, either in a planar arrangement or shaped over a three-dimensional cavity, at least one lamination (30, 31) comprising at least a first and second different dry plies, at least partially stacked to form a dry, planar or three-dimensional preform, each ply being fibrous and the plies mutually differing in terms of their structure, their positioning on the preform, the fibres composing them and/or the geometry of the ply, wherein at least one ply is laid in a non-woven form and has a plurality of unidirectional fibre layers laid on top of each other with a different angular orientation of the fibres, and/or at least one ply is woven; b) thermoforming the preform, the thermoforming step taking place, when the preform has been draped in a planar arrangement in step a), in a three-dimensional cavity of a first mold to impart a three-dimensional shape thereto; and c) impregnating, with at least one polymer, the preform thus thermoformed inside a mold, the preform being moved, if it is draped in a planar arrangement in step a), from the first thermoforming mold to a second mold for the impregnation step.
