“…It is fabricated by sandwiching a thick AF as core material between two thin alloy sheets as facing sheets. With this sandwich structure, the AFS can provide specific strength, better dimensional stability, improved damping and acoustic insulation properties compared with the simply AF [14,15], as the core foam bears shear load meanwhile the face sheets carry an axial load and resist against bending [16].…”

Aluminum Foam Sandwich panels were fabricated via liquid diffusion welding and glue adhesive methods. The Microstructure of the Aluminum Foam Sandwich joints were analyzed by Optical Microscopy, Scanning Electron Microscopy, and Energy Dispersive Spectroscopy. The metallurgical joints of Aluminum Foam Sandwich panels are compact, uniform and the chemical compositions in the diffusion transitional zone are continuous, so well metallurgy bonding between Aluminum face sheet and foam core was obtained. The joining strength of an Aluminum Foam Sandwich was evaluated by standard peel strength test and the metallurgical joint Aluminum Foam Sandwich panels had a higher peel strength. Moreover, a three-point bending fatigue test was conducted to study the flexural fatigue behavior of Aluminum Foam Sandwich panels. The metallurgical joint panels have a higher fatigue limit than the adhesive joining sandwich. Their fatigue fracture mode are completely different, the failure mode of the metallurgical joint is faced fatigue; the failure mode for the adhesive joint is debonding. Therefore, the higher joining strength leads to a longer fatigue life.

“…The collisions and impacts that occur in various disasters pose a tremendous threat to the safety of human lives and property. Therefore, different structures [1–3] that offer high-deformation and energy absorption capabilities are in high demand. For this purpose, a typical honeycomb plate, as a lightweight, high-strength structure [4–6], has been applied in many fields [7–10].…”

For developing lightweight and high-strength biomimetic sandwich structures, this study investigates the influence of honeycomb dimensions and forming methods on the mechanical properties of beetle elytron plates relative to honeycomb plates via compression experiments and the finite element method. The results indicate that the trabecular-honeycomb core structure in beetle elytron plates can increase the compressive strength by approximately 50% and double the energy absorption capacity of honeycomb plates with the same material costs. Furthermore, the influence of three types of forming methods on the compressive properties of beetle elytron plates is investigated by comparing the different deformation modes of these structures with those of honeycomb plates. Based on these findings, application recommendations regarding the forming methods of beetle elytron plates are presented to facilitate the structural design and preparation techniques according to the performance requirements of different fields, which will accelerate the industrial application of these biomimetic structures.

“…Lately, several studies have been conducted on thermomechanical behavior of asymmetric sandwich composite structures under buckling loading. [42][43][44][45][46][47][48][49] It is known that symmetrical lay-ups are required to avoid thermal deformations during the cure. Contrarily, when an asymmetric structure is manufactured (face sheets not symmetric) then at the manufacturing stage, there will be thermal residual stresses.…”

In this study, finite element modeling is performed to investigate the compressive failure of the composite sandwich structures with layered composite shells. An embedded debond area between the layered composite shell and the foam core is assumed as a defect. The composite shells are several plies of equal thickness Kevlar, carbon fiber composite, and E-glass composite with epoxy resin. Three different lay-ups, namely, (0°/90°/0°/90°/0°/90°), (45°/−45°/0°/90°/60°/−30°), and (60°/−30°/90°/0°/30°/90°) are considered for symmetric and asymmetric sequences. The work focuses on the importance of cohesive zone model versus the previously conducted numerical simulation and experimental results for buckling of sandwich composite structures. This enables one to account for delamination growth between shells and core and improve the correlation results with those of experiments. It has been shown that not only the cohesive model is capable of demonstrating delamination propagation, but it also correlates very well with the experimental data. By compiling user-defined cohesive mesoscale model in Abaqus simulation, the local and global buckling of the face-sheets can be precisely detected and response of sandwich structure becomes mesh independent, while mesh size is reduced.
