Purpose: The purpose of this paper is to investigate the buckling behavior of the load-carrying support structure of a wind turbine blade. Design/methodology/approach: Experimental experience has shown that local buckling is a major failure mode that dominantly influences the total collapse of the blade. Findings: The results from parametric analyses offer a clear perspective about the buckling capacity but also about the post-buckling behavior and strength of the models. Research limitations/implications: This makes possible to compare the response of the different fiber-reinforced polymers used in the computational model. Originality/value: Furthermore, this investigation leads to useful conclusions for the material design optimization of the load-carrying box girder, as significant advantages derive not only from the combination of different fiber-reinforced polymers in hybrid material structures, but also from Kevlar-fiber blades.
