Aluminium Honeycomb Sandwich Panel
Bending performance of Aluminium Honeycomb Sandwich Panel
Carbon fiber aluminum honeycomb panels have to bear bending loads, and because the wall panels are under bending loads, the stress conditions are relatively complex, and there are compression zones and tension zones, so it is necessary to study the response of honeycomb panels under bending loads. Researchers have found that by improving the performance of the binder, the bending bearing capacity of the honeycomb panel can be improved to a certain extent, but after all, the improvement of the binder performance has a certain limit. Compared with the strong metallurgy formed by brazing, the latter has a higher bonding strength.
The structural parameters of the honeycomb panel will also affect the bending performance. The increase in the ratio of the honeycomb core wall thickness to the honeycomb hole side length will lead to an increase in bending strength and stiffness, especially when the change in bending strength is more obvious. The height of the honeycomb core has opposite effects on the compression performance and bending performance. The higher the honeycomb core, the better the bending performance but the worse the compression performance. Therefore, we can improve its bending characteristics by selecting the appropriate honeycomb structure size and using brazing instead of bonding.
The mechanical properties of the materials used in the honeycomb panel and the structural parameters of the honeycomb sandwich panel will directly affect the overall mechanical properties of the manufactured honeycomb panel. With the development of science and technology and the rapid development of numerical simulation technology, the degree of influence of these structural parameters on the mechanical properties of honeycomb sandwich panels can be comprehensively considered.
Outstanding advantages
01
Light material, high strength, high rigidity, stable structure, good wind pressure resistance
Aluminium honeycomb sandwich panel have been widely used in building exterior wall decoration due to their many advantages such as lightweight, high strength, and high rigidity. The weight of honeycomb sandwich panels with the same rigidity is only 1/5 of that of aluminum panels and 1/10 of that of steel panels. The aluminum honeycomb panel with a total thickness of 15mm, a panel of 1.0mm, and a bottom plate of 0.8mm weighs only 6 kg/m2. The interconnected honeycomb core is like countless I-beams. The core layer is distributed and fixed in the entire panel surface, which is not easy to produce shear, making the panel more stable, and more resistant to bending and compression. Its wind pressure resistance greatly exceeds that of aluminum-plastic panels and aluminum veneers, and it is not easy to deform and has good flatness. Even if the honeycomb panel is large, it can achieve extremely high flatness.
02
Outstanding sound insulation, heat insulation, fire prevention and shockproof functions
Because the honeycomb core in the honeycomb composite panel is divided into many closed chambers, the airflow is blocked, and the heat and sound waves are greatly hindered, so it has the effect of heat insulation, heat preservation, and sound insulation. The sound source of 100-3200HZ can reach 20~30dB, and the thermal conductivity is 0.104-0.130W/M.K. Therefore, the energy absorption capacity of aluminum honeycomb panels is 150-3500KJ/M2, which is an ideal energy-saving material. In case of heavy rain, the noise is particularly loud when raindrops hit the aluminum veneer or aluminum-plastic panel, and the honeycomb panel avoids this situation.
03
Flat appearance, diverse colors, and durability
Honeycomb panels of different specifications and sizes have extremely high flatness and are not easy to deform.
The main advantages of Aluminium honeycomb sandwich panel are as follows
The panels on both sides of the aluminum honeycomb panel are high-strength aluminum panels, and the inner layer is a special hexagonal aluminum honeycomb, which serves as the core plate adhered to the sandwich structure and bears pressure in the tangential direction. These dense honeycombs that restrain each other are like many small I-beams, which can disperse the pressure from the panel direction, make the panel evenly stressed, and ensure that the panel can still maintain a high degree of flatness when it is large in area.
Strength-weight ratio
Due to the continuous support of the core to the surface, the surface panel can give full play to its ability to withstand tensile or compressive loads.
Stiffness-to-weight ratio
Honeycomb panel manufacturers can achieve a stiffness-to-weight ratio by selecting appropriate surface panels and sandwich materials for structural parts that are mainly subjected to bending.
Excellent sound insulation and heat insulation performance
Honeycomb panel manufacturers' honeycomb itself does not have sound insulation and heat insulation performance, but the honeycomb sandwich structure has good sound insulation and heat insulation performance.
Good shock absorption performance
Because there are many dense honeycombs that restrain each other, it is like many small I-beams that can disperse and bear the pressure from all sides. Therefore, it has strong earthquake resistance..
The standard panel thickness is 40 mm
The polished aluminum panel is a 5000 series alloy with maximum strength and corrosion resistance.
The panel thickness can range from 6 mm to 80 mm
The thickness of the aluminum back plate ranges from 0.3mm, 0.5mm, 0.8mm, 1.0mm, etc.
