METHOD OF MANUFACTURING A WIND TURBINE BLADE BY EMBEDDING A LAYER OF PRE-CURED FIBRE REINFORCED RESIN

摘要

The present invention relates to a method of manufacturing a wind turbine blade or a part of a wind turbine blade. The method comprises arranging at least one of layer of uncured resin pre-impregnated fibres, called prepregs, and at least one layer of cured fibre reinforced resin in an at least partly overlaying relationship, and curing the resin of the at least one layer comprising uncured resin. The at least one layer of cured fibre reinforced resin is assembled with at least one layer of uncured resin-preimpregnated fibres prior to being placed on a moulding surface. The method may e.g. be used to manufacture a wind turbine blade shell member or a wind turbine blade spar member. The invention further relates to a wind turbine blade shell member or a wind turbine blade spar member manufactured by such a method. The invention further relates to a pre-form for use in a wind turbine blade, the pre-form comprising at least one of layer of uncured resin pre-impregnated fibres and at least one layer of cured fibre reinforced resin in an at least partly overlaying relationship.

1. A pre-form for use in a wind turbine blade, the pre-form comprising:
at least one of layer of uncured resin pre-impregnated fibres; and at least one layer of fully cured fibre reinforced resin in an at least partly overlaying relationship with the at least one layer of uncured resin pre-impregnated fibres, wherein the layers are arranged in a sequence which is starting and ending with a cured layer, the layers being assembled together to define the pre-form, the pre-form held together by tackiness of the at least one layer of uncured resin pre-impregnated fibres.
