✦ Synopsis
A new method for fabricating closed cellular materials containing polymers has been developed. Polystyrene powder particles coated with a nickel᎐phosphorus alloy layer by electroless plating, were sintered at high temperature. A metallic closed cellular material containing polymer was then fabricated. Scanning electron microscope observations and energy dispersive X-ray spectroscopy analysis indicated that polymer remains in the cells after heat treatment. The compressive tests of this material show a low Young's modulus and high-energy absorption. Ultrasonic measurements showed that the attenuation coefficient of this cellular material is very large and changes with increasing temperature.
