摘要： The disclosure relates to a method of manufacturing a fibre reinforced composite, wherein the surface of the fibre reinforced composite modified by using a laser radiation. In particular, the pre-treatment is performed before a bonding process. Time-consuming and dust generating grinding of the surface can be avoided.

摘要： The present invention relates to an interlayer sheet (20) for a spar cap (10) comprising: a first fibre layer (30) comprising a first plurality of fibres, having a first upper fibre surface (31) and a first lower fibre surface (32), a second fibre layer (40) comprising a second plurality of fibres, having a second upper fibre surface (41) and a second lower fibre surface (42). The first fibre layer (30) is arranged on top of the second fibre layer (40), such that the first lower fibre surface (32) is in contact with the second upper fibre surface (41). The first fibre layer (30) is of a different characteristic than the second fibre layer (40). Furthermore, the present invention relates to a spar cap (10) for a wind turbine blade, comprising a plurality of pre-cured fibre-reinforced elements including at least a first pre-cured fibre-reinforced element (60) and a second pre-cured fibre-reinforced element (70);

摘要： 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 precured 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 p recured 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.

摘要： The invention provides a method for manufacturing a wind turbine blade shell part (24, 26). The method comprises laying up one or more outer skin fibre layers (81) in a wind turbine blade shell part mould (80); providing a spar cap part (82) comprising one or more precured elongate reinforcement elements, the spar cap part (82) having a first end (82a) and a second end (82b); gradually bringing the spar cap part (82) into contact with one or more of the outer skin fibre layers (81), starting from the first end; laying up one or more inner skin fibre layers in contact with the spar cap part; and providing liquid resin into the mould and curing the resin, thereby obtaining the wind turbine blade shell part. The invention also provides a wind turbine blade obtainable by the method.
