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 manufacturing processes of composite and nanocomposite metal foams.

“…Nevertheless, an increase in the energy absorption capacity is expected with increases in the plateau stress [24]. Thus, the energy distribution of the metal foam under compressive forces is with respect to the friction that is formed given the contact and collapse mechanism of the cell walls [25]. The polystyrene filling of the spherical-shaped aluminum foam pores increases the energy distribution limiting fracture, buckling, and bending of cell walls during the deformation.…”

In this study, the crushing behavior of spherically shaped aluminum foam pieces coated with polystyrene and uncoated under compression load was investigated. The spherical shaped aluminum foam parts produced by powder metallurgy with diameters of 8 mm and 10 mm were coated with polystyrene by the injection molding process. The obtained foam elements were then subject to quasi-static compression tests at room temperature with a constant crosshead speed of 1 mm/min. According to the experimental results, polystyrene coatings increased the energy damping capacity of the foams by approximately 115% while increasing the density by about 50%.

“…Figure 4. Comparison of energy absorption curvesMany references[9][10][11][12][13] show that the compressive yield stress of aluminum foam is within 20 MPa, and the energy absorption per unit volume does not exceed 30 MJ / mm 3 , as shown in Figure4 (b). Therefore, the energy absorption per unit volume of PLA and PLA-Cu materials is much higher than that of aluminum foam materials, indicating that PLA and PLA-Cu materials can replace aluminum foam materials in some applications.…”

In order to study the static compression mechanical properties and energy absorption characteristics of 3D printing polylactic acid (PLA) and copper powder filled polylactic acid (PLA-Cu) materials, quasi-static compression tests were carried out at room temperature using CMT5105 microcomputer controlled electronic universal testing machine. The results show that the stress-strain curves of the two materials show the compression characteristics of porous materials, and have typical three-stage characteristics. The compression bearing capacity of PLA-Cu materials is significantly higher than that of PLA materials. When the strain is 80 %, the energy absorption per unit volume of PLA material can reach 78.27 MJ / mm3. After adding copper powder, the energy absorption per unit volume of PLA material can be increased by 51.7 %, indicating that 3D printing products have excellent impact resistance and buffer energy absorption characteristics.
