Abstract

The present invention relates to a preform for a wind turbine blade, the preform having a slab-like structure with a mainly flat, wide and elongated shape having a longitudinal direction, where the preform comprises a stacking of layers of mainly unidirectional fibre tows (11) placed in the longitudinal direction, a number of separation fibre layers (12) inserted in the stacking and with predetermined distances in the stacking between separated layers of the mainly unidirectional fibre tows, as well as matrix resin. It further relates to a method of manufacturing a preform for a wind turbine blade.
