Composite wind turbine blade and method for manufacturing same
First Claim
1. A wind turbine blade comprisinga plurality of longitudinal composite members each having a fiber and resin layer around a predetermined cross-sectional shape and each comprising at least one longitudinal outer surface and at least one longitudinal mounting surface,each of the outer surfaces of the plurality of longitudinal composite members corresponding to a different portion of a desired airfoil shape,the plurality of longitudinal composite members assembled to form an interior structure of the wind turbine blade such that the outer surfaces of the composite members form at least a majority of the airfoil shape;
- andwherein the fiber layer of the longitudinal composite members comprises axial features capable of intermeshing with an adjacent fiber layer in the assembly.

Abstract
A wind turbine blade may include a plurality of longitudinal composite members each having a fiber and resin layer around a predetermined cross-sectional shape and each comprising at least one longitudinal outer surface and at least one longitudinal mounting surface, each of the outer surfaces of the plurality of longitudinal composite members corresponding to a different portion of a desired airfoil shape, the plurality of longitudinal composite members assembled such that the outer surfaces of the composite members form at least a majority of the airfoil shape. An outer skin may be provided. The composite members may be made up of transportable segments. A method of assembly may include transporting the segments to a desired location such as an installation site for assembly of the wind turbine blade at the installation site.
