“…Nevertheless, few studies on the performance of CNT‐reinforced AMCFs were reported. Duarte et al used an innovative method combining colloidal treatment and powder technology to prepare CNT‐reinforced AMCFs, which guarantees a good distribution and integral structure of CNTs in the Al matrix. Zhang et al prepared CNT‐reinforced closed‐cell Al foams by improved melt foaming method.…”

The compression‐compression fatigue performance of carbon nanotube (CNT) reinforced aluminium matrix composite foams (AMCFs) were investigated. The ε‐N curves of AMCFs are composed of three stages (the elastic, strain hardening, and rapid accumulation stages), while the fatigue strain of AMCFs accumulates very rapidly in stage III compared with Al foams. The fatigue strength of AMCFs with CNT contents of 2.0, 2.5, and 3.0 wt% increases by 6%, 44%, and 102% than Al foams, respectively. Different from Al foams' deformation of layer‐by‐layer, the main failure modes of AMCFs are the brittle fracture and collapse of pores within significant shear deformation bands under fatigue loading. The uniform distribution of CNTs and good interfacial bonding of CNTs and Al matrix is the important factor for the improvement of fatigue properties of AMCFs.

“…In Fig.2a the compressive stress-strain curves of samples are shown. Similar to all of the porous metals, the compressive curves of the samples in this study exhibit three distinct regions (i) linear elastic, (ii) plateau and (iii) densification regions [2].…”

Abstract. In this research work, closed aluminum foams produced by powder metallurgy method, the aging heat treatment was performed on samples to evaluate the effect of copper as an alloying element and TiB2 as reinforcement on the mechanical properties of aluminum foams. The results indicated that, in this alloy foam, TiB2 particles play minor role on the mechanical properties, while the aging heat treatment enhanced the mechanical properties of the foam samples dramatically. In addition, the size of age hardening precipitates was smaller than the external reinforcement.

“…Furthermore, optimizing the cell size leads to increasing the surface area, improving plateau stress and the ability to absorb energy. Lately, a study that introduced dispersion of carbon nanotubes [60] and graphene nano-sheets in liquid metal strengthened the cell walls and led to enhancement of the plateau stress and energy absorption of Al-foam. Hence, it is required to understand their deformation behavior under compression at different strain rates for metal foam applications to absorb impact.…”

The present work was addressed to the closed-cell aluminum (Al)-silicon carbide (SiC) particles (15 wt.%) with graphene (0.5 wt.%) reinforced hybrid composite foam, which was produced through the melt route process. Under the strain rates ranging from 500 s −1 to 2760 s −1 , the compression deformation behavior of hybrid composite foam was executed. The compression results disclosed that plateau stress along with energy absorption of produced hybrid composite foam are heightened with strain rates and is also discovered to be responsive to the relative density under the confront domain of experiments. Analysis of Variance was deployed for optimizing parameters such as strain rates, mass, density, relative density, and pore size. Furthermore, the contribution of each optimized parameters on plateau stress and energy absorption were observed.
