Abstract
A wind turbine blade shell component is made by providing a plurality of first pultrusion plates formed of a first fiber material, and a plurality of second pultrusion plates formed of a second fiber material. The first and second pultrusion plates are stacked in a hybrid pattern that includes a first section containing a plurality of the first and second pultrusion plates having a length shorter than an entire length of a spar cap for a wind turbine blade shell, and a core section having a continuous unbroken length of the second fiber material corresponding to an entire length of the spar cap. The stacked pattern is arranged on blade shell materials in a mold for the blade shell component and is bonded with the blade shell materials to form the blade shell component.
