Abstract: In an aspect, the present disclosure is directed to a composite structure. The composite structure includes a three-dimensional (3-D) grid structure and at least one monolithic skin layer at least partially enveloping and securing the grid structure. As such, the grid structure is configured to stabilize the composite structure under at least one of: static local buckling and dynamic global buckling.

Abstract: The present disclosure is directed to a method of forming a root portion of a wind turbine rotor blade. A plurality of alignment pins coupled to an alignment plate is aligned with a first set of a plurality of insert cavities defined by a prefabricated panel. Each alignment pin is positioned within one of a first set of a plurality of installation apertures defined by the alignment plate. The prefabricated panel and the alignment plate are coupled such that each alignment pin is positioned within one of the first set of the plurality of insert cavities. A first adhesive is placed in each of the second set of the plurality of insert cavities. A first set of inserts are placed into a second set of the plurality of insert cavities. The first set of inserts and the alignment plate are coupled, and the first adhesive is cured.
