Abstract
A wind turbine blade component is made by providing a plurality of first pultrusion plates formed of a first pultrusion fiber material, and a plurality of second pultrusion plates formed of a second pultrusion fiber material. The first and second pultrusion plates have a length corresponding to an entire length of a spar cap for a wind turbine blade shell. The first and second pultrusion plates are stacked in a hybrid pattern that contains both first and second pultrusion plates, and the stack is arranged on blade shell material in a mold for the blade shell. The stacked hybrid pattern of first and second pultrusion plates is bonded with the blade shell materials to form an integral blade shell and bonded spar cap component.
