Abstract

A blade of a wind turbine is provided. The blade includes different layers, which are used to build up the three-dimensional shape of the blade. Resin is applied to connect the layers while the blade is manufactured. A reinforcement structure is arranged close to the surface of the blade and at a resin-rich-section of the blade, where a certain amount of resin is gathered during the manufacture of the blade.

Claims

exact text as granted — not AI-modified
1 .- 10 . (canceled) 
     
     
         11 . A blade of a wind turbine, comprising:
 a plurality of different layers, which are used to build up a three-dimensional shape of the blade; and   a reinforcement structure, which is arranged close to a surface of the blade and at a resin-rich-section of the blade,   wherein resin is applied to connect the plurality of layers while the blade is manufactured, and   wherein a certain amount of resin is gathered at the reinforcement structure during the manufacture of the blade.   
     
     
         12 . The blade according to  claim 11 ,
 wherein the reinforcement structure is arranged along at least a part of the trailing edge, and   wherein the reinforcement structure is arranged along at least a part of the leading edge, and   wherein the reinforcement structure is arranged close to a plurality of sharp corners of the blade.   
     
     
         13 . The blade according to  claim 11 , wherein the reinforcement structure is arranged along at least a part of the trailing edge. 
     
     
         14 . The blade according to  claim 11 , wherein the reinforcement structure is arranged along at least a part of the leading edge. 
     
     
         15 . The blade according to  claim 11 , wherein the reinforcement structure is arranged close to a plurality of sharp corners of the blade. 
     
     
         16 . The blade according to  claim 11 , wherein the blade is manufactured by an applied Vacuum Assisted Resin Transfer Moulding process, which uses a closed-mould-structure to encapsulate the blade while the resin is applied. 
     
     
         17 . The blade according to  claim 16 , wherein the resin-rich-section is defined by an inner surface of the closed-mould-structure and by the shape of the blade. 
     
     
         18 . The blade according to  claim 11 , where the reinforcement structure is a rail. 
     
     
         19 . The blade according to  claim 11 , wherein the reinforcement structure includes an angle in its cross section, while the angle is chosen in a way that the reinforcement structure is attached in a form-fit-manner to the plurality of layers of the blade. 
     
     
         20 . The blade according to  claim 19 , wherein the angle is 90°. 
     
     
         21 . The blade according to  claim 11 , wherein the reinforcement structure is a laminate structure and a pre-casted laminate structure. 
     
     
         22 . The blade according to  claim 11 , wherein the reinforcement structure is a laminate structure. 
     
     
         23 . The blade according to  claim 11 , wherein the reinforcement structure is a pre-casted laminate structure. 
     
     
         24 . The blade according to  claim 11 ,
 wherein the reinforcement structure comprises a plurality of channels or tubes, and   wherein the applied resin penetrates the reinforcement structure.   
     
     
         25 . The blade according to  claim 11 , wherein the reinforcement structure is an integrated part of the blade. 
     
     
         26 . The blade according to  claim 24 , wherein the reinforcement structure is an integrated part of the blade. 
     
     
         27 . The blade according to  claim 26 , wherein the reinforcement structure is arranged close to a surface of the blade.
