Acoustic 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 کاملAluminum Foams Processed by Rapid Prototyping for Lightweight Structures
The demand for faster and lighter land transportation for the troops has increased the need for more efficient structures. Sandwich panels form one type of efficient structure enabling the application of steel, aluminium or composites in the construction. Cellular metals for sandwich structures have been available for decades (Ashby 1998, Fleck 1998, and Gibson 1997), but new opportunities are ...
متن کاملCreep of aluminum syntactic foams
Aluminum syntactic foams with densities of 1.2–1.5 g/cm3 were deformed at 500 ◦C under constant uniaxial compressive stresses ranging from to 14 MPa. The foam creep behavior is characterized by a short primary stage and a long secondary stage where the strain rate is constant and inimum, followed by a tertiary stage at high stresses. The minimum strain rate varies with stress according to an ap...
متن کاملComposite and Nanocomposite Metal Foams
Open-cell and closed-cell metal foams have been reinforced with different kinds of micro- and nano-sized reinforcements to enhance their mechanical properties of the metallic matrix. The idea behind this is that the reinforcement will strengthen the matrix of the cell edges and cell walls and provide high strength and stiffness. This manuscript provides an updated overview of the different manu...
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...
