摘要： The present invention relates to a stiffening element (1) and a method for manufacturing of a stiffening element (1) of composite material, which stiffening element (1) is provided for attachment to a curved shell surface (9). A substantial flat blank (29) of composite material comprising a first (13) and a second (15) essentially parallel elongated edge is provided for forming in the web (3) of the stiffening element (1) at least one rounded bulge (19) having a conical form tapering from the first edge (13) to a first folding line (17). Thereby is achieved a curved flange (5), which first folding line (17) essentially merges with an apex of the rounded bulge (19).

摘要： 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). The male tool (1) and the fiber composite laminate (2) are then rotated relative to one another so that the fiber composite laminate (2) is brought into contact with the intermediate web (1b) of the male tool (1) in a first rotational movement, and brought into contact with the second flange (1c) of the male tool (1) in a second rotational movement. The fiber composite laminate (2) hardens on the male tool (1), and the finished beam is separated from the tool (1). The invention also relates to a beam of fiber composite material fabricated according to the method.

摘要： A method and an apparatus for conforming a blank onto forming surface sections of a forming tool by drawing a vacuum against an elastic vacuum bag for transmitting forming forces from the elastic vacuum bag to the blank. The elastic vacuum bag includes at least one bag section having a different stiffness than other bag sections. The at least one bag section is an elongated bag section having a stiffness larger than that of surrounding bag sections. The location of the elongated bag section of the elastic vacuum bag corresponds, when the elastic vacuum bag after completion lies against the forming surface sections having the blank in between, with an elongated forming surface section of the forming tool where the blank requires a forming force being larger than that of the surrounding bag sections.
