Abstract

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).
