Classification of Foam Structures
Following from: Highly porous cellular foams
In order to correctly evaluate the mechanical properties, as well as the thermal properties (such as the conductive and radiative properties), the foam structure must be modeled as close as possible to real three-dimensional (3D) foam geometry.
Description of Foam Morphologies
We consider some typical structures of highly porous cellular materials. Cellular structures can be classified morphologically, distinguished by two types of materials: (1) open cell carbon, metallic, or ceramic foams and (2) closed cell foams, such as polystyrene or polyurethane foams. The foam structure varies significantly depending on whether it is open cell or closed cell foam (Figs. 1 and 2).
