World's first material to reach theoretical stiffness limits
US-based researchers have developed a foam-like pyramid-cross-cell structure claimed to be ''maximally stiff in all directions'' by theoretical bounds. Named 'Isomax', the solid foam is a stiff substance with air pockets and is claimed to be uncommonly strong for its mass. Its lightness, strength, and versatility could be applied to building, aerospace, and packaging industry, researchers said.
