Due to its excellent physical and mechanical properties, Aluminum Foam for Automobile Structural Parts can be used as both structural materials and functional materials. In general, it has dual functions of function and structure. It is a multifunctional engineering material with excellent performance that integrates function and structure. Because Aluminum Foam for Automobile Structural Parts itself has many physical properties in mechanics, thermodynamics, acoustics and electromagnetics. Foam metal structural materials are used to absorb energy by using the ultra light structure of bubbles and the characteristics of cushioning and energy absorption. Therefore, Aluminum Foam for Automobile Structural Parts, as a good light energy absorbing component, is more and more used in the automotive field.
The application of Aluminum Foam for Automobile Structural Parts are as follows:
1: Passenger compartment floor
Aluminum based foam aluminum has good energy and sound absorption characteristics and can be used
A kind of "sandwich" Aluminum Foam for Automobile Structural Parts material is used to make the automobile floor, which can effectively achieve the effect of vibration isolation and sound insulation while ensuring the strength and stiffness. Compared with the solid plate, it can reduce the noise by 2-4 times, so as to improve the comfort of the vehicle and greatly reduce the noise during the driving process.
2: Automobile front and rear anti-collision unit
The front anti-collision energy absorption of the car is between the front of the car and the cab, with different strengths metal materials, starting from the front of the car, are designed into stepped areas with different strengths. In the event of a collision, the most vulnerable front of the car will first collapse and deform, followed by the second section, and then the third section. In the process of collapse and deformation in turn, gradually maximize the absorption of impact energy generated by the collision to ensure the safety of the passenger compartment.
3: Battery box of electric vehicle
The use of Aluminum Foam for Automobile Structural Parts has excellent vibration damping, which is the electricity of pure electric vehicles.
The tank is filled with foam aluminum on the bottom plate and side panel, which can effectively absorb energy and prevent vibration, and protect the battery. If the car body collides, the side panel of the battery box collapses and absorbs energy. At the same time, the force is transferred to a certain extent through the structure, which can effectively prevent the damage of the battery cell and reduce the possibility of explosion and fire after the collision to a certain extent. Similarly, Aluminum Foam for Automobile Structural Parts has good fire protection characteristics. The treated foam aluminum can remain molten for 25 minutes at 700 ℃. Even in the case of battery burning, it can effectively form protection and win critical time for passengers to escape.
4: Local energy absorbing structure of vehicle body
With the development of new energy electric vehicles, the body structure has gradually changed from steel structure step into steel aluminum hybrid body, now all aluminum body is also increasingly mature. If the aluminum alloy body is filled with Aluminum Foam for Automobile Structural Parts, the stiffness is expected to increase by more than 1.5-2 times, and the damping and shock resistance can also increase by more than 2 times
