Lightweight structuring core material

The aerospace industry has long made use of ROHACELL® as a lightweight, structural core material that also reduces the cost of sandwich materials because of its process reliability. Because of its outstanding material properties— excellent creep and shear properties, even under prolonged dynamic stress—ROHACELL® has proven to be an excellent structural foam in fiber composite components not only for the aviation industry, but also to form the most important components of the helicopters: the rotor blades.
