摘要： A wind turbine blade includes an elongated blade body extending from a root to a tip with a trailing edge, whereby at least one beam-like reinforcement means is integrated in the blade body adjacent to the trailing edge for reinforcing the region of the trailing edge, with the reinforcement means extending partly over the length of the blade body, wherein the reinforcement means is a pre-casted carbon beam including carbon fibers.
