    摘要： Method for producing at least a part of a root of a wind turbine rotor blade, wherein at least two precast root segments (1, 2, 3) are arranged next to each other and at least one layer of a reinforcement fabric (12, 13) is arranged at an outside (8) and at an inside (7) of the root segments (1, 2, 3), respectively, which reinforcement layers (12, 13) bridge a gap (6) between two neighbouring root segments (1, 2, 3), whereafter a resin (14) is applied for embedding the reinforcement layers (12, 13) and for filling the gap (6), which resin (14) is cured, wherein for providing a reinforcement means (9) in the final root (11), a preformed reinforcement element (10), which is permeable for the resin (14) and which comprises several fiber mats (15) is arranged in the gap (6) and is embedded in the resin (14) penetrating through the reinforcement element (10).

    摘要： A method of manufacturing a wind turbine rotor blade part (36), the method comprising the following steps:
    -providing a placeholder (76) comprising a core member (10) and a sleeve (12), wherein the core member (10) comprises a longitudinal direction (14), a circumferential surface (16), a front end (18) and a back end (20), and the sleeve (12) comprises a peel ply layer (22), wherein the sleeve (12) covers the circumferential surface (16) and the back end (20) of the core member (10) and is affixed to the back end (20) of the core member (10);
    -arranging the placeholder (76) together with reinforcing fibres and a matrix material in a mould (84);
    -curing of the matrix material, so that the placeholder (76) is embedded in a fibre-reinforced composite material (34).
