Compressive property and energy absorption characteristic of open-cell SiCp/AlSi9Mg composite foams

A novel approach to obtain in-situ growth carbon nanotube reinforced aluminum foams with enhanced properties

“…Foams absorb energy mainly through the buckling, yielding, fracture and the friction of cell wall when they contact with each other [6,8]. It can be seen that the ball-milled composite foams exhibit superior energy absorption capacity at any same strain compared to the other two samples, which is consistent with compressive test results.…”

“…In recent years, the composite foams reinforced by ceramic reinforcements like Al 2 O 3 [6], SiC [7] have been increasingly reported, and these foam materials possess the strengthened cell wall and the enhanced energy absorption capacity. However, the aggregation of the ceramic reinforcements in the cell wall and poor bonding between matrix and reinforcements are the major problems, sometimes resulting in the deformation brittleness and a decrease in the energy absorption efficiencies of composite foams [7,8]. Thus, it is necessary to develop the new favorable reinforcement of Al foams and to exploit the properties of composite foams.…”

Static three-point bending behavior of aluminum foam sandwich

“…Actually, the failure of AFS perhaps happen in several modes, e.g., face sheet cracking, face sheet wrinkling, core shear, indentation and delamination [13,14]. However, just delamination of them is focused to investigate in the previous studies.…”

Fabrication and compressive behaviour of an aluminium foam composite

“…As for Al foams, improving its mechanical properties is still a priority in current research. Many methods have been developed to improve the mechanical properties of open-cell Al foams, such as changing the cell proportion, size, shape and distribution [33][34][35], improving the Al matrix's mechanical properties [36][37][38][39][40][41], heat treatment [42][43][44], changing specimen size (height/diameter ratio) [45,46], filling with other materials or filling in tubes to form engineering materials with a sandwich structure [47][48][49][50]. In general, the filled materials are always polymeric, such as rubber and polyurethane, which have no elastic limit [47].…”
