Abstract
Wind turbine blade (1) comprising a first blade part (2) and a second blade part (3), said blade parts (2, 3) being bonded by bonding means forming a bond (4). To reduce peel stresses of the bond and reduce the risk of crack formation, an edge portion of the bond (4) is covered by a low elastic modulus adhesive joint (5) bridging a gap between the first blade part (2) and the second blade part (3).

1-9. (canceled)
A wind turbine blade comprising a first blade part and a second blade part, said blade parts being bonded by a high modulus adhesive forming a bond,
- wherein an edge portion of the bond is covered by a low elastic modulus adhesive joint bridging a gap between the first blade part and the second blade part.
A method for manufacturing a wind turbine blade, said method comprising the steps of:
- providing a first blade part and a second blade part,
- bonding the first and second blade parts by a high modulus adhesive to form a bond, and
- comprising the further step of covering the bond by a low elastic modulus adhesive joint bridging a gap between the first blade part and the second blade part.
