Applications of aluminium honeycomb panels

Applications of aluminium honeycomb panels

Aluminium honeycomb panels are widely used in the aviation manufacturing industry as an important lightweight material, and they have also been used in railway vehicles around the world for a long time, and their use is quite extensive, such as the French TGV series and the Italian ETR series high-speed trains. China has only started to use aluminium honeycomb panels in recent years, and although certain results have been achieved, the scope of application is still very limited, and the understanding of the characteristics and scope of application of honeycomb laminated materials still needs to be further strengthened and expanded.

Aluminium honeycomb panel is a composite material made of aluminium honeycomb core and surface material bonding. In summary, aluminium honeycomb panel has the following basic characteristics.

(1) Light weight, high specific strength, especially high bending stiffness, the same quality of the aluminium honeycomb plate its bending stiffness is about five times that of aluminium alloy.

(2) has a very high surface flatness and high temperature stability, easy to shape and not easy to deformation, aluminum honeycomb panels can not only be made into flat panels, and can be manufactured into double bending, single bending panels, made into vehicle parts after disassembly and assembly is convenient.

(3) Excellent corrosion resistance, insulation and environmental adaptability, can adapt to various harsh operating environments of railway rolling stock and passenger cars; in addition, according to the need, these panels can be used to paint the surface or surface paste fire board treatment, to achieve good decorative, fire resistance.

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

(5) High fire rating, meeting the requirements of Class A in the International Intermodal Fire Protection Standard UIC 564-2-199l "Fire Protection and Fire Fighting Rules for Railway Coaches or Similar Vehicles for International Intermodal Transport".

(6) Smoke density after encountering a fire meets the high grade international railway fire protection standard, with good self-extinguishing properties; low exothermic value, able to form a refractory layer, which can reduce the smoke and toxic gases released, with excellent environmental performance.

(7) Excellent molding manufacturing process, can meet the requirements of complex shape and high stability requirements of railway vehicle interior parts.
