Abstract
The shaping of the fibrous texture is at least partly achieved by applying a deformable layer or strip, such as a cloth, made from a material having a thermal expansion coefficient different from that of the material constituting the fibrous texture. The layer or strip is stretched over the fibrous texture or is held in position against the texture by being wound over in order to obtain the degree of compaction wanted for the fibrous texture. The texture is densified by chemical vapor infiltration of the material constituting the matrix of the composite.
