The invention relates to a method of producing a turbine blade half (1,2) using resin infusion moulding. According to the invention said method comprises the steps of - providing a mould (3) for a turbine blade shell with fibre mats (4), - placing a strengthening member (6) over the fibre mats in the mould; - placing a air-impermeable sealing layer (17) over the fibre mats and against the strengthening member; - introducing a curable resin in the fibre mats under reduced pressure, including in the area below the strengthening member; and - curing the resin to form a turbine blade half, said turbine blade half comprising a turbine blade shell attached to the strength ening member. The invention also relates to a turbine blade half, a method of producing a turbine blade (123), and to a turbine blade. |
