Pressure vessels are formed on a hollow aluminum mandrel having an external surface of a configuration corresponding to the desired internal shape of the vessels. An impervious vessel inner liner is formed on the mandrel as by electro-deposition, and the vessel wall is then formed by winding filamentary reinforcing material on the inner lining, impregnating such material with a resinous material, curing the resinous material, and then removing the hollow aluminum mandrel chemically by use of an aqueous solution of caustic soda.
