The method comprises the following successive steps: - producing an initial preform (1) on a mandrel by winding threads without generating shrinking, - cutting the initial preform (1) to the correct length, - placing the assembly provided beforehand with internal drainage means (61) and pressurisation means (6) into a female mould (2), - bringing the preform assembly to a softening temperature and pressurising said assembly at both ends until it is deformed by a diametrical increase in its dimensions - bringing the impregnation resin to polymerisation temperature and pressure in order to allow the workpiece to consolidate, its external shape becoming consistent with the internal shape of the mould (2), - opening the mould and removing the workpiece from the mould, - machining the final shapes of the composite workpiece.
