The invention relates to a method for manufacturing an article made of a composite material consisting of a polymer matrix reinforced by a fibrous structure. The method includes the steps of placing the fibrous structure (10) on a substrate (20) forming a moulding surface, covering the structure with a mating mould (30), and compacting said structure by moving the surface of the mating mould toward the surface of the substrate. The method is characterised in that the substrate (20) includes a cylindrical portion (21) and a wall (22, 23) positioned radially relative to the cylindrical portion (21), and the mating mould includes two portions (31, 32 or 33) which are mobile relative to one another and which are moved toward the axis of the cylindrical portion (21) and towards the radial wall (22, 23) of the substrate (20), respectively. The invention can be used in particular for manufacturing the fan casing of a turbojet engine.
