1. A process for manufacturing a cylindrical composite component comprising:
producing a fibrous texture in the form of a strip by three-dimensional or multi-layer weaving,
winding the fibrous texture on several superimposed lathes on a mandrel with a profile corresponding to that of the component to be manufactured so as to form a fibrous preform,
densifying the fibrous preform with a matrix,
wherein, when the fibrous texture is wound on the mandrel, a web comprising a fugitive material filled with carbon nanotubes is interposed between the adjacent turns of the fibrous texture.
