Claim Text:
1. A wind turbine blade for a rotor of a wind turbine ( 3 ) comprising a profiled contour ( 8 ) formed by a hollow shell body made of fibre-reinforced resin, wherein the hollow shell body comprises a first shell body part ( said beam body ( 17 ) comprising a beam core ( 22 ) having a first ( 24 a ) and a second ( 24 b ) mutually interspaced outer lateral faces and a first ( 52 ) and a second ( 53 ) mutually interspaced end faces, each of the lateral faces being covered by a web ( 50 ) of fibre-reinforced polymer, the first end face being covered by fibre-reinforced polymer of the first beam flange ( 16 a ) and the second end face being covered by fibre-reinforced polymer of the second beam flange ( 16 b ), the beam body ( 17 ) being integrally formed with and connected to the first beam flange ( 16 a ) by two opposite first transition areas ( 32 a ) comprising fibre-reinforced resin and integrally formed with and connected to the second beam flange ( 16 b ) by two opposite second transition areas ( 32 b ) comprising fibre-reinforced resin, the first beam flange ( 16 a ) being connected to an inner surface ( 18 ) of the first shell part ( 13 ) and the second beam flange ( 16 b ) being connected to an inner surface ( 19 ) of the second shell part ( 14 ), characterized in that the transition areas ( 32 a , 32 b ) comprise notch-reducing means comprising a rounded or chamfered connection between each of the lateral faces ( 24 a , 24 b ) and each of the adjacent end faces ( 52 , 53 ) of the beam core ( 22 ).
