The new foam aluminum material is a new type of strategic functional structural material. It is a foam-like ultra-light metal material with numerous pores dispersed in the metal aluminum matrix. It integrates multiple functions and has many excellent properties, such as permeability , Sound absorption, damping, vibration reduction, electromagnetic shielding, etc. At the same time, the new foam aluminum material also has good mechanical properties of strength and rigidity, especially its unique response characteristics to compressive loads, and has excellent energy absorption. It is a kind of impact absorption that is more excellent than polymer foam materials. Can and protective materials.
The excellent properties of the new foam aluminum material mainly include: ultra-lightness, high strength ratio, mechanical properties, strong compressive strength, fire-resistant insulation 100% flame retardant, equivalent to marble, and good thermal insulation performance; thermal stability Good, comparable to concrete, not easy to deform when heated; good sound absorption and sound insulation, a fire-resistant, sound-absorbing material that does not reduce performance in humid environments, with excellent noise reduction coefficient; there is no moisture absorption phenomenon, and no acoustic performance due to moisture Reduced; corrosion resistance is very good, the service life is more than 30 years; damping and energy absorption shock absorption are comprehensive and ideal shock absorption materials; the main chemical composition of the new foam aluminum material is aluminum alloy and its oxide, which can be 100% % Recycled and will not cause any pollution to the environment.
As the new foamed aluminum material reflects the new trend of multidisciplinary interpenetration of structural materials and functional materials, it has shown a wide range of development space in the field of materials, and has a very wide range of applications in civil, industrial, transportation, aviation, aerospace, military and defense fields. Prospects, the scope of application continues to expand. In particular, foam aluminum sound barriers, foam aluminum sound absorption and noise reduction, foam aluminum building decoration, foam aluminum electromagnetic shielding, foam aluminum sound insulation panels, foam aluminum sound-absorbing panels, and foam aluminum composite panels are all building materials with good performance and a large amount of use.
