The aluminum honeycomb panel is becoming more and more popular in the building materials market this year. Why? Do you want to know? Please listen to Bangli Building Materials Manufacturer to tell you the reason step by step.
Honeycomb panel is made of two thinner panels, which are firmly bonded on both sides of a thick honeycomb core material, also known as honeycomb sandwich structure. In addition, the honeycomb panel also refers to a large number of cut-off waveguides welded together to form a cut-off waveguide array, forming a large opening area, and at the same time to prevent electromagnetic wave leakage of the panel.
The Drawing of Aluminum Honeycomb Panel Structure
Woodgrain aluminum honeycomb sandwich panel with honeycomb structure as core layer is inspired by natural hexaguon honeycomb. Because of its unique structure, the aluminum honeycomb plate made of an aluminum alloy not only has the lightest mass in other materials of the same volume but also has very good stiffness and overall stability, as well as sound insulation performance. Aluminum alloy has no radioactivity, and will not volatilize any harmful gas to human health. It can also be completely recycled and reused, saving resources and energy, and reducing environmental pollution to the lowest level, which makes aluminum honeycomb panel become a new material of energy-saving, environmental protection, and health features.

Unique structural style and advantages of aluminum honeycomb panel
(1) Lightweight, low density:
The core layer of the honeycomb panel is a typical porous structure, and the continuous polygonal cells are arranged regularly and periodically, so the cross-sectional area of the solid part of the honeycomb panel is very small, so its density is relatively small compared with other sandwich materials. Because the density of the honeycomb panel is far less than that of the laminated plate, steel plate, and other common panels, its mass is also the lightest when its volume is the same. The mass of aluminum honeycomb panel is only 9% of the same volume of FRP laminated plate, 11% of the same volume of the steel plate, and 23% of the same volume of aluminum alloy plate. This makes the aluminum honeycomb panel can save a lot of energy when it is used in aircraft. Low density and lightweight make the honeycomb plate meet the requirements of "lightweight, energy-saving and environmental protection" for aerospace engineering vehicles and transportation vehicles.
(2) High strength and rigidity:
From the mechanical point of view, the structure of honeycomb panel is similar to that of many I-beams connected together, the panel is similar to the flange of I-beams, which mainly bears the in-plane load, while the honeycomb core is similar to the web of I-beams, whose main role is to bear the shear stress, connect and support the upper and lower plates. But the web of honeycomb core is different from that of I-beam. It is not a thin reinforcement but a dense reinforcement. The core layer is distributed and fixed in the whole plate, and the height of the core layer is much larger than the thickness of the plate, which makes the section moment of inertia multiply, and the overall stability also increases greatly while improving the overall stiffness.
(3) Good shock resistance and shock absorption.
When the honeycomb panel is impacted out of the plane, the impact force can be transformed into the plastic deformation energy of the honeycomb core, so it can effectively absorb the impact energy. Through the self dropping ball impact test on the aluminum honeycomb panel, the area and depth of the dent in the impact part are observed, and no crack is found in the impact part, which shows that the aluminum honeycomb plate has good toughness and strong impact resistance, can absorb most of the energy through its own deformation and has a good damping effect.
(4) Heat and sound insulation.
For example, aluminum is a good conductor of heat and sound. But the unique structure of the honeycomb panel makes the honeycomb panel have good heat insulation and sound insulation performance. The core is a kind of porous structure, and the pore space accounts for most of the space. For example, the aluminum honeycomb panel made of 0.1mm thick aluminum foil is 51.96x48.00x12.20mm, and the solid part only accounts for 4% of the total volume. After the honeycomb core and the panel are combined into a honeycomb plate, the cell becomes a six prism-shaped airtight space. The air layer between the upper and lower panels is also divided into many airtight cells, which prevents the airflow. The form of heat convection and radiation is very difficult to transmit in this structure, and the propagation of sound waves is also greatly limited, so the honeycomb plate has better heat insulation and sound insulation performance.
(5) Good fire and moisture resistance.
The panel and core layer of aluminum honeycomb panel are made of aluminum alloy, which is non-flammable and can play a very good role in fire resistance. In addition, aluminum alloy has good chemical stability, corrosion resistance, and moisture resistance.
(6) Good formability, optional thickness.
The thickness of the arc-shaped aluminum honeycomb plate can be selected at 5-200mm according to the actual needs, and the shape can also be made into a flat plate, single curved panel, or double-curved panel according to the specific requirements. The aluminum honeycomb plate not only has good formability but also is not easy to deform after forming.
(7) No pollution, energy conservation, and environmental protection.
Aluminum alloy is the material for making aluminum honeycomb panels. It is neither radioactive nor volatilizing any harmful gas which is harmful to human health. It can also be completely recycled and reused, saving resources and energy, which is very in line with the requirements of energy conservation and environmental protection. In addition, by reducing the quality of transportation tools, the honeycomb plate improves power performance, reduces fuel consumption, and reduces exhaust pollution while ensuring the strength.
(8) Beautiful and easy to clean.
The aluminum alloy panel of the aluminum honeycomb panel can be used directly, and can also be coated with various colors or patterns by different coating layers.
