Abstract
A metallic 3-dimentional micro-honeycomb structural material containing heat resistant polymer for smart systems has been developed. Heat resistant polymer 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 3-dimentional micro-honeycomb structural material containing heat resistant polymer was then fabricated. The compressive and damping tests were carried out to measure the mechanical and damping properties of this material, respectively. The results showed that the stress-strain curve had a liner region, long plateau region and wavy region, and the sintering temperatures of the specimens affected the compressive strength of each specimen. The damping capacity of this material were shown to be very large. These results indicate that this metallic closed cellular material can be utilized as a material for energy-absorbing and passive-damping systems.
