Wind Blade Manufacturers Testing Honeycomb Core
Wind turbine blade manufacturers are running qualification trials on aramid honeycomb sandwich cores for nacelle covers and shear webs, targeting weight reductions of 12 to 18% versus balsa wood core on blades exceeding 80 meters. Vestas and Siemens Gamesa have both disclosed pilot programs evaluating honeycomb core in blade components since 2024, alongside foam and balsa alternatives already in commercial use. If even a handful of blade platforms move from pilot to qualified production by 2028, wind energy would become the second-largest application within five years, reshaping a demand base that has been almost entirely aerospace for decades.
