Summary:

Cellular solids (also known as porous solids) comprise a special class of materials. Such materials are common in nature; wood, cork, sponge and coral are examples. Recently man has also made his own cellular solids. For example, many honeycomb-like materials, made up of parallel, prismatic cells, are used for lightweight aerospace structural components. Polymeric foams have been used in everything from disposable coffee cups, packaging materials, to the crash padding of an aircraft cockpit. Advanced techniques now exist for foaming not only polymers, but metals and ceramics as well. These newer foams are increasingly used for catalysts (chemical), preforms for metal-matrix composites, thermal insulators and thermal shock resistant materials (thermal), acoustic dampers (acoustic), cushions, vibration reducers, and systems for absorbing the kinetic energy from impacts (mechanical). Their uses exploit the special combination of properties offered by cellular solids, properties which, ultimately, derive from their cellular structure. The objective of this proposed research is to develop processing techniques to produce metallic foams with controlled cellular structures and to understand and model the mechanical behavior of this special class of materials.
