摘要： A method for manufacturing a structural element (20) of a wind turbine blade (3), the method comprising:
- arranging a first segment (21) and a second segment (22) of the structural element (20) adjacent to each other;
- arranging a joining portion (23) between the first segment (21) and the second segment (22), wherein the joining portion (23) is made of or comprises a fibre lay-up (25);
- encapsulating the joining portion (23) and, at least partially, the adjacent segments (21, 22) in a vacuum bag(27);
- applying vacuum to the vacuum bag (27) for pulling together the first segment (21), the second segment (22) and the joining portion (23);
- infiltrating the fibre lay-up (25) with polyurethane resin (30) and/or ring-opening metathesis polymerization resin (30);
- curing the resin (31).-

摘要： A method for manufacturing a wind turbine blade (3, 3'), the method comprising the steps:
a) positioning (S2) an outboard blade section (9, 57, 58) at a predefined end position (50, 62, 66), the outboard blade section (9, 57, 58) comprising an outboard end portion (44, 60, 63),
b) positioning (S4) an inboard blade section (8, 56, 61) adjacent to the outboard blade section (9, 57, 58), the inboard blade section (8, 56, 61) comprising an inboard end portion (10, 59),
c) determining (S5) a deviation of a current position (45) of the inboard end portion (10, 59) of the inboard blade section (8, 56, 61) with respect to the outboard end portion (44, 60, 63) of the outboard blade section (9, 57, 58) from a nominal position (46) of the inboard end portion (10, 59) with respect to the outboard end portion (44, 60, 63), and
d) moving (S6) the inboard blade section (8, 56, 61) relative to the outboard blade section (9, 57, 58) to compensate for the determined (S5) deviation.
The complexity of the alignment procedure when aligning lengthwise blade sections can be reduced and the accuracy of the alignment increased.-

摘要： The packing table (1) comprises a three dimensionally shaped material layup surface (11) having a shape that corresponds to an inner contour of respective joining interfaces (311,321) of the blade sections (31,32) to be joined and has a center plane (C) oriented normally with respect to a longitudinal axis (L) of the wind turbine blade, wherein an axial position of the center plane (C) corresponds to a center of the joining zone (3). The shape of an inboard portion (111) of the material layup surface (11) corresponds with an inner contour of the joining interface (311) of the inboard blade section (31) and the shape of an outboard portion (112) of the material layup surface (11) corresponds with an inner contour of the joining interface (321) of the outboard blade section (32).
The packing table (1) according to the invention allows to provide a process optimization in the manufacturing of a joining adapter (2) and thus facilitates the joining of blade sections (31,32) of longitudinally split wind turbine blades.-

摘要： A method for manufacturing a wind turbine blade (3) comprising a load-carrying beam (18, 19) extending in a longitudinal direction (A) of the blade (3) and having a predetermined total length (L1), comprising:
a) aligning (S2) at least two blade sections (8, 9) with each other, each blade section (8, 9) comprising a shell (11, 12) with an outer recess (34, 44) and the outer recesses (34, 44) forming in the aligned state an overall outer recess (45) having the predetermined total length (L1), and
b) arranging (S3) a fiber lay-up (49) in the overall outer recess (45) for forming the load-carrying beam (18, 19).
Thus, the load-carrying beam can be manufactured as a continuous structural element without piecing it together. Hence, discontinuities in the material of the load-carrying beam can be avoided. Therefore, a higher structural integrity of the blade is achieved.-

摘要： The invention relates to a method for manufacturing a structural element (11, 13, 15) of a wind turbine blade (10). The method includes the step of forming of at least one injection hole (25) in at least one laminate (21.1, 21.2, 21.3, 21.4, 24.1, 24.2) provided on a top side (D) of a core material (20.1, 20.2) of a first portion (11.1, 13.1, 15.1) and a second portion (11.2, 13.2, 15.2) of the structural element (11, 13, 15) and a bottom side (E) of a core material (20.2) of the first portion (11.1, 13.1, 15.1) and the second portion (11.2, 13.2, 15.2), so that the at least one injection hole (25) is fluidically connected to the cavity (23). Further, the method includes the step of injecting adhesive (26) through the injection hole (25) into the cavity (23), curing the adhesive (26) injected into the cavity (23) and thereby forming a joint (12, 14, 16) between an end (A) of the core material (20.1) of the first portion (11.1, 13.1, 15.1) and an end (B) of the core material (20.2) of the second portion (11.2, 13.2, 15.2).
Further, the invention relates to a method for manufacturing a wind turbine blade (10). Moreover, the invention relates to the structural element (11, 13, 15) and the wind turbine blade (10).
