Manufacture of Aluminum Closed-cell Foam by ARB process using CaCO3 as the blowing agent
Metal porous foams have been eliciting much interest in recent years due to their high capacity of energy absorption. The characteristics of the pores in these materials play an important role on their energy absorption capability and other properties. This study reports the fabrication of aluminum closed-cell foams by accumulative roll-bonding (ARB) technique using calcium carbonate (CaCO3) as...
متن کاملImproving the energy absorption of closed cell aluminum foams
Closed cell aluminum foams have received much recent attention as energy absorbing materials on account of their ability to undergo extensive deformation at a relatively low stress called the plateau stress. Several studies describe the improvements in energy absorption to be obtained, relative to their empty counterparts, when foam filled tubes are crushed either quasi-statically or dynamicall...
متن کاملInvestigation of Acoustic Properties of Polymer Nanocomposites regarding Combined Sound Absorption and Insulation Characteristics
Introduction: Nowadays multiple techniques have been developed to noise control. One the most important way is the control based on sound absorption and insulation. The purpose of current study was to improve the acoustic properties of soft polyurethane foam regarding combined sound absorption and insulation characteristics. Materials and Methods: Polyacrylonitrile and polyvinylidine fluoride ...
متن کاملAcoustic damping performance of aluminum nanocomposite foams with different additive of carbon nanotubes and comparison that with conventional rockwool (Research Article)
Open cell aluminum foams have good acoustic dampening properties. In this research, in order to improve the sound damping capacity of these foams, 0.9, 1.5 and 3wt% carbon nanotubes were added to the aluminum foam. Foams were produced by the space holder method in powder metallurgy. The results showed that Al-0.9wt%CNT nanocomposite foam had the highest average sound transmission loss in the fr...
متن کاملMechanical properties of a density-graded replicated aluminum foam
The compressive mechanical properties of uniform and density-graded Al-6061 foams, produced by replication of polymer foams, are measured. hile the uniform foam shows compressive behavior characteristic of conventional (uniform) metallic foams with a near constant plateau stress, he density-graded foam exhibits a smoothly rising plateau stress. This behavior is modeled using a simple series com...
