Aluminum honeycomb panel features overview

aluminum honeycomb panelIt has many characteristics that conventional materials do not have, mainly in the following aspects:

(1)Light weight, low density: the core layer of the honeycomb panel is a typical porous structure, and the continuous polygonal cells are regularly arranged, so the cross-sectional area of the solid part of the honeycomb panel is very small, so its density is relatively small compared to other sandwich materials. Since the density of honeycomb panels is much smaller than that of ordinary plates such as laminates and steel plates, its quality is also the lightest when the volume is the same. The quality of aluminum honeycomb panel is only the same volume of glass fiber reinforced plastic laminate9%, same volume steel plate11%, the same volume of aluminum alloy plate23%. This allows aluminum honeycomb panels to save a lot of energy when used in aircraft. The low density and light weight make the honeycomb panel well meet the requirements of aerospace engineering aircraft and transportation tools for materials.“Lightweight, energy saving and environmental protection”requirements.

(2)High specific strength and good rigidity: from a mechanical point of view, the structure of the honeycomb panel is similar to that of many I-beams connected to each other. The panel is similar to the flange of the I-beam and mainly plays the role of bearing in-plane load, while the honeycomb core is similar to the web of the I-beam and its main role is to bear shear stress and connect and support the upper and lower panel pieces. However, the honeycomb core is different from the web of the I-beam, it is not thin reinforcement but dense reinforcement, the core layer is distributed and fixed in the entire plate surface, and the height of the core layer is much larger than the thickness of the panel, which makes the section moment of inertia also doubled, while improving the overall stiffness of the overall stability is also greatly increased.

(3)Good shock resistance, vibration damping and cushioning. When the honeycomb panel is subjected to out-of-plane impact, the impact force can be converted into the plastic deformation energy of the honeycomb core, so it can effectively absorb the impact energy. Through the self-falling ball impact experiment of aluminum honeycomb panel, the dent area and dent depth of the impact part were observed, and it was found that there was no crack in the impact part, which showed that the aluminum honeycomb panel had good toughness and strong impact resistance, could absorb most of the energy through its own deformation, and had good vibration reduction effect.

(4)Heat insulation, sound insulation. The material of the honeycomb panel itself does not have the performance of heat insulation and sound insulation. For example, aluminum is a good conductor of heat and sound. However, the unique structure of the honeycomb panel makes the honeycomb panel have good heat insulation and sound insulation performance. The core is a porous structure, the hole occupies the vast majority of space, with the thickness0.1mmThe specifications made of aluminum foil are51.96x48.00x12.20mmof aluminum honeycomb panels for example, the solid part only accounts for the total volume4%. After the honeycomb core and the panel are compounded into a honeycomb panel, the cell becomes a six-sided columnar closed space, and the air layer between the upper and lower panels is also divided into many closed cells, which prevents air flow. Heat is difficult to propagate in the form of convection and radiation in this structure, and the propagation of sound waves is also greatly restricted, so the honeycomb panel has better heat insulation and sound insulation performance.

(5)Good fireproof and moisture-proof performance. The panel and core layer of the aluminum honeycomb panel are made of aluminum alloy. Aluminum alloy is a non-flammable material and can play a good flame retardant and fireproof effect. In addition, the aluminum alloy itself has good chemical stability, corrosion resistance and moisture resistance.

(6)Good formability and optional thickness. The thickness of the aluminum honeycomb panel can be5-200mmChoose, the shape can also be made into flat panel, single panel or hyperboloid panel according to specific requirements. Aluminum honeycomb panel not only has good formability, but also is not easy to deform after forming.

(7)No pollution, energy saving and environmental protection. Aluminum alloy is the preparation of aluminum honeycomb panel material, it is not radioactive, nor volatile any harmful gases harmful to human health, but also can be completely recycled, reused, saving resources and energy, very in line with the requirements of energy saving and environmental protection. In addition, the honeycomb panel reduces the quality of transportation tools, improves power while ensuring strength, reduces fuel consumption, and reduces exhaust pollution while saving energy.

( 8 )Beautiful, easy to clean. The aluminum alloy panel of the aluminum honeycomb panel can be used directly, or it can be coated with different covering layers to various colors or patterns.
