“…For three-point bending (TPB), energy absorption (EA) and specific energy absorption (SEA) were found by Sun et al [17] to be largely influenced by the structural parameters in the honeycomb core, but not much by the skin thickness.…”

“…The in-plane tensile, compressive and shear strength of the HC core, have been established through experimentation [8,11,12] and using analytical models [13]. Many researchers have performed experimental and numerical investigations on the quasi-static compressive behaviors and energy absorption capacity of aluminum HC structures [6,[14][15][16][17]. The compressive strengths of square aluminum HCs are independent of the cell aspect ratio and the presence or absence of the face sheets bonding [6].…”

“…In the hexagonal aluminum HC core structure with a lesser number of cells, the boundary effect had a considerable impact on the crush strength, while the core angle showed an effect of less than 10% on the strength value. The mechanical responses in the inplane loading direction are significantly influenced by the changes in the core geometric parameters than that of the out-of-plane loading [16]. The out-of-plane crushing resistance was reported to be twice in the magnitude of their in-plane strength [18].…”

“…Attention should also be paid to additional functionalities, for example thermal and sound insulation. The use of recycled materials is an important aspect [1][2][3][4][5][6]. The core of the sandwich panel can be materials such as balsa [6,7], light concrete reinforced with PP fibres [1], polyurethane foam [3], aluminium foam [2,8,9].…”

“…The use of recycled materials is an important aspect [1][2][3][4][5][6]. The core of the sandwich panel can be materials such as balsa [6,7], light concrete reinforced with PP fibres [1], polyurethane foam [3], aluminium foam [2,8,9]. Interesting solutions for sandwich structures were also obtained using epoxy honey comb [4], expanded cork [10], epoxy resin filled with alumine tri-hydrate (ATH) particles [11], cross-linked polyvinyl chloride foam and poly(ethylene) terephthalate (PET) foam [6], and even bottle caps [5] Attempts have also been made to obtain sandwich structures containing PCM [12,13] or aerogel [14,15], but only combining the latter two materials allows us to obtain a multifunctional material, at the same time having the ability to stabilize the temperature of the insulated space and a thermal resistance much higher than the commonly available insulating materials.…”
