Abstract
The invention relates to a method of producing a shell member of fiber composite material by means of vacuum infusion, where the fiber material is impregnated with liquid polymer, and applying a mould (18) with a mould cavity. In the mould cavity a lower distribution layer (11) is placed. A fiber insertion (1) including a plurality of fiber layers is placed above the lower distribution layer (11). A first upper distribution layer (9) and a second upper distribution layer (10) are placed at a transverse distance of each other above the fiber insertion, so that at least a part of the first distribution layer overlaps a first zone (2) of the fiber insertion (1), and at least a part of the second distribution layer overlaps a second zone (3) of the fiber insertion (1), the first zone (2) and the second zone (3) being separated by an intermediate zone (6) neither overlapping the first nor the second distribution layer (9, 10). A first inlet channel (7) is placed above the first distribution layer (9), and a second inlet channel (8) is placed on top of the second distribution layer (10). Above the intermediate zone (6) of the fiber insertion (1) a semi-permeable membrane (5) is placed, w…
