Aluminum foam sandwich panel

Aluminum foam sandwich panel has excellent performance of aluminum foam material, and at the same time solves the shortcomings of low strength of single aluminum foam, it is a new functional material with excellent comprehensive performance, and has broad application prospects in the fields of automobile manufacturing, aviation, aerospace and other fields. The preparation of foam aluminum sandwich panels at home and abroad mainly adopts the adhesive and powder metallurgy foaming methods. The foam aluminum sandwich panels produced by the adhesive process have poor high temperature resistance and corrosion resistance. The use environment of the products has certain limitations, while powder metallurgy Foaming process is the main preparation method of foam aluminum sandwich panel which has been researched more deeply in recent years. In the traditional powder metallurgy foaming process, the combination of the core and the core mainly depends on the hot pressing process, the bonding strength is low, the density of the core layer powder is not ideal, and due to the size of the hot pressing mold, it cannot produce large-sized sandwich panel materials.
