摘要： A method for manufacturing a wind turbine blade, comprising the steps of:
- arranging an upper mould (8) comprising a pre-casted fibre lay-up (9") on a lower mould (23) comprising a dry fibre lay-up (24') and a mould core (46),
- applying vacuum to a space (63) between the upper and lower moulds (8, 23) and the mould core (46),
- infusing at least the dry fibre lay-up (24') and a connection region (66, 67) between the dry fibre lay-up (24') and the pre-casted fibre lay-up (9") with a resin (65), and curing the resin (65).
By having the pre-casted fibre lay-up in the upper mould, the packing and positioning of dry composite materials on top of the mould core is avoided.
