Abstract: A method for fabricating a curved beam from fiber composite material. A flat fiber composite laminate including a plurality of layers and at least two different fiber directions is formed. The fiber composite laminate is disposed in contact with a male tool includes a first flange, a second flange and an intermediate web. The male tool is curved in its longitudinal direction with a radius of curvature in such a way that the first flange has a shorter longitudinal extent than the second flange. The fiber composite laminate is brought into contact with and secured to the first flange of the male tool. The male tool and the fiber composite laminate are then rotated relative to one another so that the fiber composite laminate is brought into contact with the intermediate web of the male tool in a first rotational movement, and brought into contact with the second flange of the male tool in a second rotational movement. The fiber composite laminate hardens on the male tool, and the finished beam is separated from the tool. Also a beam of fiber composite material fabricated according to the method.

Abstract: 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.
