Interpenetrating phase composite foam based on porous aluminum skeleton for high energy absorption

This paper presents a study on mechanical response of porous aluminum skeleton/rigid polyurethane foam interpenetrating phase composites (IPCs) at different strain rates. Mechanical properties and failure mechanisms of IPC were identified. Results shown that the strain rate sensitivity of IPC is mos...
