A metallic closed cellular material containing organic materials for smart systems has been developed. Polymer powder particles coated with a nickel-phosphorus alloy layer using electroless plating were pressed into green pellets and sintered at high temperatures in a vacuum. A metallic closed cellular material containing organic materials was then fabricated. The compressive, damping and ultrasonic tests were carried out to measure the mechanical, damping and ultrasonic properties of this material, respectively. The results showed that this material had different stress-strain curves among the specimens of different cell thickness, each stress-strain curve had a long plateau region, and the sintering temperatures of the specimens affected the compressive strength of each specimen. The damping capacity and ultrasonic attenuation coefficients of this material were shown to be very large. These results indicate the this metallic closed cellular material can be utilized as a material for energy-absorbing and passive-damping systems.
