Abstract
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 layer of uncured resin pre-impregnated fibers, called prepregs, and at least one layer of cured fiber 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 fiber reinforced resin is assembled with at least one layer of uncured resin-preimpregnated fibers prior to being placed on a molding 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 layer of uncured resin pre-impregnated fibers and at least one layer of cured fiber reinforced resin in an at least partly overlaying relationship.
