The invention relates to a method of manufacturing an integral article comprising a fiber-reinforced composite material. An inner tool body ( 12 ) of a cellular plastic material is provided, onto which an airtight sheet ( 14 ) of a flexible material is applied so as to fully encompass and seal the tool body ( 12 ). A plurality of layers ( 16 ) of fiber-reinforced composite material are then applied onto the outer surface of the airtight sheet ( 14 ), and an airtight vacuum bag ( 18 ) is in turn applied onto the outer layer of the composite material ( 16 ). The vacuum bag ( 18 ) is evacuated and the layers ( 16 ) of composite material compressed. The composite material is heat treated so as to cure the same. The vacuum bag ( 18 ) is then removed from the thus formed article. To form a hollow integral tank, the formed article is provided with a hole ( 22 ), and a solvent is poured therein to dissolve the cellular plastic material. The dissolved material is then drained through the hole ( 22 ), and the airtight sheet ( 14 ) is possibly removed therethrough.
