Uni-directional porous metal fabricated by rolling of copper sheet and explosive compaction

• A new type of porous metal with uni-directional pores (UniPore) has been developed.
• Fabrication process is based on explosive compaction of copper foil.
• It is also possible to fabricate long-length samples with constant cross-section.
• Metallographic analysis and compressive tests were performed.

A new type of porous metal with uni-directional pores (UniPore) has been developed using the explosive compaction fabrication process of rolled copper foil with plastic spacers. The interface bonding in the novel UniPore metal structure has been investigated by metallographic analysis. The mechanical properties of the new rolled UniPore specimens with different porosities have been determined by experimental compressive testing in transversal and longitudinal directions.
