Paper Abstract

New methods to fabricate a metallic closed cellular material for smart materials using an isostatic pressing, spark plasma sintering (SPS) method and penetrating method are introduced. Powder particles of polymer or ceramics coated with a metal layer using electro-less plating were pressed into pellets and sintered at high temperatures by sintering at high temperature. Also these powder particles were sintered by spark plasma sintering (SPS) method. Also a many kinds of closed cellular materials with different materials of cell walls and different materials inside of the cell were tried to fabricate. The physical, mechanical and thermal properties of this material were measured. The results of the compressive tests show that this material has the different stress-strain curves among the specimens that have different thickness of the cell walls and the sintering temperatures of the specimens affect the compressive strength of each specimen. Also, the results of the compressive tests show that this material has high-energy absorption and Young's modulus of this material depends on the thickness of the cell walls and sintering conditions. The internal friction of this material was measured and the results show that this internal friction is same as that of pure aluminum.
