Abstract
The present invention includes a method for fabricating elongated wind turbine blades and wind turbine blades formed by the method. The method includes providing a first shell reinforcing fiber structure. At least one shear web reinforcing fiber structure is positioned adjacent to the first shell reinforcing fiber structure. The method includes infusing the first shell reinforcing fiber structure and shear web reinforcing fiber structure with a matrix material and curing the matrix material to form a unitary composite first shell component. Thereafter a composite second shell component is attached to the composite first shell component to form an elongated composite airfoil suitable for use as a wind turbine blade. The wind turbine blades formed include unitary components providing reduced number of adhesive joints.
