Abstract

The present disclosure is directed to a shear web for a rotor blade of a wind turbine and a method of manufacturing and assembling same. The rotor blade generally includes an upper shell member having an upper spar cap configured on an internal surface thereof and a lower shell member having a lower spar cap configured on an internal surface thereof. Further, the shear web extends between the spar caps along a longitudinal length of the blade. In addition, the shear web includes first and second outer pultruded layers at least partially encompassing a core material, wherein end portions of the first and second outer pultruded layers form compressed flanges at opposing ends of the shear web.
