Aluminum honeycomb panel with honeycomb structure for the core layer of the honeycomb sandwich plate, its inspiration from the natural hexagonal honeycomb. Aluminum honeycomb panel made of aluminium alloy which is not only because of its unique structure in the same volume of other material quality the most light, and the stiffness and the overall stability is very good, also has the noise insulation performance. Aluminum alloy that is radioactive or volatile no harmful gases which do harm to human body health, can also be fully recycling reuse, save resources and energy, and reduced the pollution to the environment to the lowest level, which makes the aluminum honeycomb panel is one kind of energy saving, environmental protection, new materials of health.
Aluminum honeycomb panel has the characteristics of many conventional materials do not have, mainly has the following several aspects:
(1) the quality of light, density is small, honeycomb panel of the core layer is a typical porous structure, perforated continuous polygon are arranged in a periodic of rules, thus honeycomb plate entity of cross-sectional area is small, so the density of its relative to other sandwich materials are also small. As the density of honeycomb panel is far less than laminated plates, steel and other common plate, its quality also is the lightest volume being the same. With the quality of the aluminum honeycomb panel is only 9% of the volume of glass fiber reinforced plastic laminated plates, with 11% of the steel plate size, with 23% of the volume of aluminium alloy plate. This makes the aluminum honeycomb panel can save a lot of energy when it is applied in the plane. Low density light honeycomb panel is very good to satisfy the space engineering with aircraft and transport of materials "lightweight, energy conservation and environmental protection".
(2) than high strength, good rigidity, from the Angle of mechanics analysis, the structure of honeycomb panel is similar to many h beam are connected together, panel similar to h-beam flange, main function under in-plane loading, which is similar to the honeycomb core web h-beam, its main function is under shear stress and the connection, support from top to bottom panel. But with the honeycomb core h beam web plate is different, it is not rare reinforced rather dense reinforcement, fixed core layer distribution throughout the panel, and the core layer height is larger than the thickness of the panel is very much, this makes the section moment of inertia is multiplied, in improving the overall stiffness of the overall stability also have risen sharply.
(3) the impact resistance, good vibration damping buffer. Honeycomb panel surface outside, hit the impact can be converted to the plastic deformation of the honeycomb core can, so can effectively absorb the impact energy. Of aluminum honeycomb panel since falling ball impact experiments, observe the dent the crashed area, indentation depth, found that the impact site no crack, explain the toughness of the aluminum honeycomb panel is good impact resistance is stronger, can through own deformation to absorb most of the energy, the damping effect is good.
(4) the heat insulation, sound insulation. Manufacturing honeycomb panel without heat insulation, sound insulation performance of material itself, such as aluminium are good conductors of heat and sound. But the unique structure of honeycomb panel, honeycomb panel heat insulation, sound insulation performance is good. Nest core is a kind of porous structure, perforated accounted for most of the space, to the specifications of the thickness of 0.1 mm aluminium foil is 51.96 x48.00 x12.20 mm aluminum honeycomb panel as an example, the entity part accounts for only 4% of the total volume. Composite honeycomb panels, honeycomb core and panel perforated as six prismatic sealed space, the air layer between the panels were points in many airtight perforated, to prevent the air flow, it is difficult for heat convection and radiation in the form of communication in this structure, in which sound waves have also been very limited, so the honeycomb panel has good heat insulation, sound insulation performance.
(5) the fire prevention, moistureproof performance is good. Aluminum honeycomb panel panel and core layer are made of aluminum alloy, aluminum alloy is not flammable material, can have very good flame retardant fire prevention effect. In addition, aluminum alloy itself good chemical stability, corrosion resistance, resistance to moisture.
(6) good formability, thickness is optional. The thickness of the aluminum honeycomb panel can choose according to actual needs in the 5-200 - mm, shape can be made according to the specific requirements or hyperbolic panel plate, single panel. Aluminum honeycomb panel not only good formability, and not easy to deformation after forming.
(7) no pollution, energy conservation and environmental protection. Aluminum alloy is the material preparation of aluminum honeycomb panel, it is not radioactive, nor are any volatile harmful gases which do harm to human body health, also can be completely recycled, repeated use, save resources and energy, very accord with the requirement of energy conservation and environmental protection. In addition, the honeycomb panel by reducing the quality of the means of transport, while ensuring strength and improve the power performance, reduce fuel consumption, at the same time reduces the exhaust pollution in saving energy.
