  • Publication number: 20070039689
    Abstract: The present invention relates to a method for the manufacture of a composite article comprising a composite plate (1) and at least one fitting (4). The method is characterized by the steps of arranging at least one former on said composite plate (1), arranging at least one fitting (4) on said composite plate (1), producing a lay-up by applying a composite material layer (9) least partly covering an external surface of the former and of the fitting, and curing the layup in a curing process. After curing, said composite material layer (9) forms the walls of a stiffener and at least partly encloses the fitting so as to support it in a predetermined position.

  • Publication number: 20060216480
    Abstract: This invention concerns a method for fabricating a curved beam from fiber composite material. A flat fiber composite laminate (2) comprising a plurality of layers and at least two different fiber directions is formed. The fiber composite laminate (2) is disposed in contact with a male tool (1) comprised of a first flange (1a), a second flange (1c) and an intermediate web (1b), which male tool (1) is curved in its longitudinal direction with a radius of curvature R in such a way that the first flange (1a) has a shorter longitudinal extent than the second flange (1c). The fiber composite laminate (2) is brought into contact with and secured to the first flange (1a) of the male tool (1).

  • Publication number: 20050191919
    Abstract: The present invention relates to a method for the fabrication of a former for manufacture of composite articles. The method is characterized by the following steps: forming a wetted water-soluble fiber composite on a master tool such that the fiber composite material lies against a surface area of the master tool, allowing the water-soluble fiber composite to dry on the master tool and removing the dry water-soluble fiber composite from the master tool, wherein the dry fiber composite forms the walls of the thus fabricated former.
