Dow Formulated Systems says its Compaxx 700 offers a high run-to-run consistency leading to predictable mechanical properties that structural engineers can use to create more precise blades.
The Compaxx 700 foam core for wind turbine blades is the first in a line of new core materials that will help manufacturers extend blade life with high performance sandwich composites. The materials come from Dow Formulated Systems, a business unit of The Dow Chemical Co.
Sandwich-panel fatigue testing following Germanische Lloyd requirements showed the foam core exhibits long-term dynamic behavior and shear-strength properties that build lightweight composites with excellent mechanical strength and fatigue resistance. These properties, coupled with a peel strength about three times higher than the historical reference of core material PVC 60 kg/m3, create a tight core-to-skin bond necessary for blade durability.
In addition, the foam core has a high run-to-run consistency leading to predictable mechanical properties that structural engineers can use to create more precise blades. The Compaxx system is available globally in commercial volumes.
