Title:
CHORDWISE LAY-UP OF FIBRE SHEET MATERIAL FOR TURBINE BLADES
Document Type and Number:
WIPO Patent Application WO/2013/007263
Kind Code:
A3
Abstract:
The present invention relates to a fibre sheet material and method of laying up fibre sheet material to manufacture wind turbine blades. The invention further comprises a blade manufactured by the method as well as a use of such a blade. One aspect relates to an oblong fibre sheet material(26)for wind turbine blades, where a surface layer (14) is having a width, which in the lateral direction is broader than a lateral, unidirectional layer (10), and lengthwise side faces of at least the surface layer is provided with a thinning of a thickness of the layer to obtain favourable joints. Another aspect concerns manufacturing a wind turbine blade shell comprising laying fibre sheet (26) materials in a blade mould (20), where the sheet materials lengthwise are positioned in a direction corresponding to a chordwise direction of a turbine blade direction of the mould and overlapping in a spanwise direction. The effect obtained is a significant reduction in the amount of waste material compared to laying fibre sheets in the spanwise direction.
