Abstract

A new material for damping and energy-absorbing has been developed using a powder particle assembling technique. Powder particles of polystyrene coated with nickel-phosphorous alloy layers using electroless plating were assembled and sintered at high temperature. A closed cellular solid structure containing polystyrene was then constructed. The mechanical and ultrasonic properties of this cellular solid were measured at room temperature and at high temperatures. The compressive tests show that Young's modulus of this cellular solid is very small as are the changes due to increasing temperature, and the cellular solids have a high energy absorption. Ultrasonic measurement showed that the attenuation coefficient of this cellular solid is very large and would change due to increasing temperature. These results indicate that this cellular solid can be used for energy absorbing and passive damping systems.
