Abstract: Provided is a composite structure having a longitudinal direction and a transverse direction, having a longitudinally extending fiber insertion having a plurality of fiber layers, a first surface, a second surface, a first side, and a second side; a fiber insertion first zone at the first side of the fiber insertion; a fiber insertion second zone at the second side of the fiber insertion; an intermediate zone separating the first zone and the second zone; a distribution medium adjacent at least one of the first side and the second surface of the intermediate zone, the distribution medium comprising a resin distribution network; and a cured resin impregnating at least the resin distribution network and the fiber insertion.

Abstract: A use of a core block for an impregnation process as well as a composite structure comprising such a core block is described. The core block has a first surface and a second surface, and a number of first grooves is formed in the first surface of the core. Furthermore, a number of second grooves is formed in the second surface of the core. The first grooves have a first height (h1) and a bottom, and the first grooves and the second grooves are part of a resin distribution network formed in the core block. The distance (t) between the bottom of the first grooves and the second surface of the core block is of such a size that the core block is flexible along the first grooves. Additionally, the sum of the first height and the second height is larger than the thickness of the core block, and at least one of the first grooves in the first surface of the core block crosses at least one of the second grooves in the second surface of the core block.
