Aluminum scrap-based multi-layer hybrid and functionally graded composite foam and its manufacturing process

摘要

The present invention relates to multilayer, hybrid and functionally graded aluminum foam obtained from aluminum scrap from beverage cans and its manufacturing process. This multi-layer aluminum bandage foam can be used in bulletproof body armor in many areas such as aviation, armaments industry, motor vehicle and rail system, reduction of impact effect in fast trains and cars, vibration damping, absorption of energy during impact and shock, electromagnetic shielding, as an air cushion plate during Carrying trucks like tanks, providing soundproofing on highways and also flame retardant applications.
