Aluminum foam sandwich composite panels produced by Henan Chalco Corporation has excellent special properties and multiple application potentials, but the strength of a single foamed aluminum material is low. Therefore, foamed aluminum is often combined with dense metal plates to form a composite structure to make structural parts. At present, the common layered sandwich structure material is characterized in that the material's shell or panel is aluminum or fiber reinforced composite material, and the core layer is mostly light wood, foam polymer material, etc. The core layer generally has a honeycomb structure, and the board / Core connection mainly depends on physical connection methods such as bonding.


The Aluminum foam sandwich composite panels is the lightest composite structure with a given structural requirement, but this structure is subject to many restrictions in application. The main problem is that water and other fluids can easily penetrate into the board, which affects the service life of the Aluminum foam sandwich composite panels. More importantly, the Aluminum foam sandwich composite panels layer has anisotropy, which results in the tensile strength and other properties of the material under different loading There are large differences in direction. The core layer of the Aluminum foam sandwich composite panels is foamed aluminum or foamed aluminum alloy, and the upper and lower layers are aluminum plates or other metal thin plates. The sandwich panel composite structure composed of a metal panel and a foamed aluminum core has the outstanding characteristics of light weight, high specific stiffness and specific strength, and has good energy absorption, shock absorption and electromagnetic shielding properties.
The main application areas of Aluminum foam sandwich composite panels in Henan Chalco: automotive manufacturing, rail transportation, aerospace, national defense.
