Aluminum honeycomb plate material is widely used in aviation manufacturing industry

　　Aluminum Honeycomb MaterialAs an important lightweight material, it is widely used in the aviation manufacturing industry and has been used in foreign railway vehicles for a long time,aluminum honeycomb panelIt has a wide range of uses, such as the French TGV series and the Italian ETR series high-speed trains. Domestic only in recent years began to use aluminum honeycomb panels, although achieved certain results, its application is still very limited, the characteristics of honeycomb sandwich materials and the scope of application of understanding to be further strengthened and expanded.

Aluminum honeycomb board material is a composite material bonded by aluminum honeycomb core material and surface material. In summary, aluminum honeycomb board has the following basic characteristics:

(1) aluminum honeycomb plate material light weight, high specific strength, especially high bending stiffness, the same quality of aluminum honeycomb plate bending stiffness is about 5 times the aluminum alloy.

(2) Aluminum honeycomb plate material has high surface flatness and high temperature stability, easy to form and not easy to deform, aluminum honeycomb plate can not only be made into a flat panel, but also can be made into a double curve, single panel, made into vehicle parts after easy disassembly.

(3) excellent corrosion resistance, insulation and environmental adaptability, can be adapted to the railway EMU and passenger car all kinds of harsh environment; In addition, aluminum honeycomb plate material according to the need, this kind of plate can be used surface paint or surface paste fire board treatment, to achieve good decoration, fire resistance.

(4) Unique resilience, aluminum honeycomb board material can absorb vibration energy, and has good sound insulation and noise reduction effect.

(5) The aluminum honeycomb board material has a high fire rating and meets the-level requirements in the International Intermodal Fire Protection Standard UIC564-2-199l Fire Protection and Fire Protection Regulations for Railway Passenger Cars or Similar International Intermodal Vehicles.

(6) The smoke density after the fire meets the high-grade international railway fire protection standard, with good self-extinguishing; the heat release value is low, can form a fire-resistant layer, can reduce the release of smoke and toxic gases, has excellent environmental performance.

(7) excellent molding manufacturing process, aluminum honeycomb plate material can meet the railway vehicle interior parts complex shape, high stability requirements.
