Methods for Making Cellular and Porous Metals with Controlled Pore Structure

Porous materials with controlled pore structure are in high demand for many industrial applications. Cellular metals are metal foams with periodic cells. The periodic cells comprise either micro-truss lattices or prismatic materials. Manufacturing of porous and cellular materials with pre-designed topologies for optimum properties presents tremendous challenges. Inexpensive manufacturing methods that enable control of the topology are needed. This technology describes a new method for the manufacturing of porous and cellular materials with controlled pore structure.

The method of production of porous materials in this technology is based on novel powder processing and micro-fabrication, and controlled chemical reaction sintering techniques. The porous material can be used as functional components and filter for: fuel cells, destruction of chemical and biological weapons agents, diesel exhaust clean up. They can also be used as structural materials for aerospace, automobile, sporting goods, etc.

Stage of Development
A patentability opinion is being considered at this time. This technology is part of an active and ongoing research program. It is available for developmental research support/licensing under either exclusive or non-exclusive terms.
