Abstract

A method for manufacturing a blade spar for a wind turbine blade includes positioning a first spar segment having a first adhering portion; positioning a second spar segment having a second adhering portion at the first spar segment such that the first adhering portion and the second adhering portion are at least partially overlapping, wherein an adhesive is at least partially provided between the overlapping adhering portions; providing at least one fiber layer impregnated with an uncured resin on the outer surfaces of the first and second spar segments at least in the joint region of the first and second spar segments; and simultaneously curing the adhesive and the resin, thereby fixating the first and the second spar segments to each other.
