Abstract
This invention relates to a method of manufacturing a wind turbine blade and a wind turbine blade thereof. A central core element and a plurality of side core elements are sandwiched between first layers and second layers of a first fibre material. The central core element is spaced apart from the side core elements to form a first and a second recess. This sandwich structure is then impregnated with a first resin and cured in a first step. Layers of a second fibre material of a first and a second main laminate are laid up in the first and second recesses. The first and second main laminates are then impregnated with a second resin and cured in a second step.
