Abstract
A rotor blade for a wind turbine includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. The blade segments each have at least one shell member defining an airfoil surface and an internal support structure. The internal support structure of the first blade segment includes a beam structure that structurally connects with the internal support structure of the second blade segment via a receiving section. The rotor blade further includes one or more pin joints positioned on at least one of internal support structures of the blade segments. Further, at least one of internal support structures is constructed, at least in part, of a resin material having a plurality of fibers cured therein. The fibers are arranged with varying fiber orientations along a span of the rotor blade at locations of the pin joint(s).
