The invention relates to the manufacture of a composite material part by shaping a fibrous reinforcement texture and densifying the texture by chemical vapor infiltration of the material constituting the matrix of the composite through the porosity of the texture. Before densification, the texture is separated from an adjacent structure, such as an adjacent surface of a tool inside which the texture is held, or another texture, by means of an inserted layer of fabric produced in a refractory material having a thermal expansion coefficient different from that of the constituent material of the texture.
