Wind turbine blade comprising metal filaments and carbon fibres and a method of manufacturing thereof

摘要

Wind turbine blade has a longitudinal direction and includes a shell structure made of a fiber-reinforced polymer material including a polymer matrix and reinforcement material comprising a plurality of carbon fiber layers embedded in the polymer matrix. At least a portion of the shell structure is formed of a laminate 6 comprising at least one metal filament layer 15, 18 comprising metal filaments and being sandwiched between two carbon fiber layers 16, 16; 17, 18 comprising carbon fibers only. The carbon fiber layers are arranged contiguously with the metal filament layer.

1. A wind turbine blade having a longitudinal direction and including a shell structure made of a fibre-reinforced polymer material including a polymer matrix and reinforcement material comprising a plurality of carbon fibre layers embedded in the polymer matrix characterised in that at least a portion of the shell structure is formed of a laminate comprising:
at least one metal filament layer comprising metal filaments, a first side, and a second opposite side; and a plurality of carbon fibre layers, each carbon fibre layer comprising carbon fibres only and the carbon fibre layers being arranged on top of each other, wherein the carbon fibre layers abutting the metal filament layer are positioned on the first side of the metal filament layer and on the opposite second side of the metal filament layer.
