The lightweight structure, energy absorption and noise control of the new foamed aluminum material make it widely used in the automotive and transportation industries. Automobiles are increasingly becoming lighter, lower energy consumption, safer and more comfortable. For this reason, it is necessary to use materials with low density, good overall performance, and high recycling rate. The excellent performance of the new foamed aluminum material determines that it has a wide range of uses and broad application prospects. Especially in the application of the automobile manufacturing industry, the new foam aluminum material is considered to be a promising material for future automobiles and other transportation vehicles.
In order to protect the earth's environment and natural resources, it is necessary to improve the fuel efficiency of automobiles. Reducing its own weight is an excellent way to improve fuel efficiency. The methods to reduce the weight of a car include improved structure and lightweight materials. The former has roughly come to an end, and only the latter has the potential to be tapped. This provides a good opportunity for the development and application of new foam aluminum materials.
Foreign studies have shown that the rigidity of the car frame is strengthened by using components made of foamed aluminum new materials. In automobile manufacturing, about 20% of the body structure can be made of new foam aluminum materials. A medium-sized car using foam aluminum parts can reduce weight by about 27.2 kg, while simplifying the structural system and reducing the number of parts by at least 1/3 , Reduce the cost of the car. The new foam aluminum material is a good energy absorber, and the energy absorbed per unit volume can reach 6-9M J. The strong energy absorption capacity shows its superiority as a bumper material for automobiles. The use of suitable components made of new foam aluminum materials in the impact area of the car can control the deformation of the maximum energy consumption. The use of new foam aluminum materials as deformable materials in the front and rear of the car passenger seat can also improve safety.
The new foam aluminum material is heat-resistant and flame-retardant, and at the same time, it does not release toxic gases when heated. Therefore, the new foam aluminum material is used in transportation to replace foam plastic or foamed resin materials, which can increase the service life and reduce maintenance. At the same time, it also eliminates the harmful gases produced by traditional materials in vehicle accidents, greatly reduces the loss and casualties in traffic accidents, and also plays a role in environmental protection.
