Problems solved by technology

[0003] The invention provides a new type of high-performance porous metal composite material for automobiles to solve the problem that the existing foamed aluminum or aluminum-magnesium alloy materials have extremely poor pore uniformity, and through-holes and closed-cells coexist, which cannot effectively reduce the weight of automobiles. At the same time, the unevenness of the pores will also cause uneven bearing capacity of the material; the polyurethane sandwich panel material is used in the automotive field, its strength and flame retardancy are poor, which seriously affects the driving safety of the car and other issues

Description

【Technical field】 [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a novel high-performance porous metal composite material for automobiles. 【Background technique】 [0002] As the concept of "energy saving and environmental protection" has attracted more and more attention from the society, lightweight has also been gradually applied to the field of ordinary cars, which can have excellent fuel-saving performance while improving handling. According to existing literature and patent reports, the way to reduce the weight of automobiles is to use a large number of lightweight porous materials on the body, such as alloy porous materials such as aluminum and magnesium, and polyurethane sandwich panel materials. The manufacturing costs of these materials are relatively high. Alloy porous materials such as aluminum and magnesium can only be foamed by thermal melting of the bulk metal, unlike metals such as porous iron and nickel, which ...
