Wind turbine blade manufacture

Abstract

A wind turbine blade is disclosed. The wind turbine blade comprises a core material, a first fibre reinforced plastic and a spar cap comprising a third fibre reinforced plastic, and a shear web comprising a second fibre reinforced plastic. The first fibre reinforced plastic, the second fibre reinforced plastic, and the spar cap each comprise a chemically disassemblable polymer. Further disclosed is a method of disassembling such a wind turbine blade by exposing the wind turbine blade to an acid to cause the chemically disassemblable polymer to disassemble; and recovering fibres from at least of one of the first fibre reinforced plastic, the second fibre reinforced plastics and the third fibre reinforced plastic.
