Zusammenfassung:	A method is provided of manufacturing a wind turbine blade shell member (36, 38), the method comprising the steps of providing a blade mould (96) for the blade shell member, arranging one or more layers of fibre material in the moulding cavity to provide a fibre layup (97), and providing a pre-manufactured spar cap member (62). The surface of the spar cap member is treated with a primer composition to provide a primer-treated surface. Heat is then applied to the primer-treated surface of the spar cap member to provide an activated surface, for improving the bonding in a subsequent resin co-infusion of the spar cap member and the fibre layup. L'invention concerne un procédé de fabrication d'un élément de coque de pale d'éolienne (36, 38), ce procédé comprenant les étapes consistant à : fournir un moule de pale (96) pour l'élément de coque de pale ; agencer au moins une couche de matériau fibreux dans la cavité de moulage pour fournir une superposition de fibres (97) ; et fournir un élément de semelle de longeron préfabriqué (62). La surface de l'élément de semelle de longeron est traitée avec une composition d'apprêt afin de fournir une surface traitée par apprêt. De la chaleur est ensuite appliquée sur la surface traitée par apprêt de l'élément de semelle de longeron, afin de fournir une surface activée destinée à améliorer la liaison dans une co-infusion ultérieure de résine de l'élément de semelle de longeron et de la superposition de fibres.
