Pultruded components for a shear web of a wind turbine rotor blade

摘要

The present subject matter is directed to a rotor blade assembly for a wind turbine having a pultruded component at an interface of a shear web and a spar cap. More specifically, the rotor blade assembly 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. A shear web extends between the spar caps along a longitudinal length of the blade. Further, the shear web includes a first end and a second end. The first end is secured to the upper spar cap at a first interface and the second end is secured to the lower spar cap at a second interface. In addition, the shear web includes at least one pultruded component configured at either or both of the first or second interfaces between the first and second ends and the upper and lower spar caps, respectively.
