Beschreibung
Zusammenfassung:	The present invention relates to a spar cap for a wind turbine blade comprising a plurality of pre-cured fibre-reinforced elements and a plurality of interlayers. The plurality of pre-cured fibre-reinforced elements include a first pre-cured fibre-reinforced element and a second pre-cured fibre-reinforced element and the plurality of interlayers include a first interlayer comprising a first plurality of fibres embedded in a first cured resin. The first interlayer is being arranged between the first pre-cured fibre-reinforced element and the second pre-cured fibre-reinforced element. The first plurality of fibres have a first elastic modulus, the first cured resin has a second elastic modulus, the first and/or second pre-cured fibre-reinforced elements have a third elastic modulus, and the first interlayer has a fourth elastic modulus. The ratio between the first elastic modulus and the second elastic modulus is between 1:4 and 4:1 and/or the ratio between the third elastic modulus and the fourth elastic modulus is between 1:4 and 4:1.
