    Abstract:

    The out-of-plane compressive behavior of the closed-cell aluminum foam plate, 3 types of empty corrugated plates, and the sandwich panels with 3 types of closed-cell-aluminum-foam-filled corrugated aluminum plates bonded by epoxy resin was investigated. The results show that the aluminum-foam-filled corrugated plates can increase the compressive strength and energy absorption capacity significantly, and obtain more stable mechanical properties. Aluminum-foam-filled corrugated plates have an obvious three-dimensional effect in compression. The smaller the strength of sandwich panel, the more obvious the three-dimensional extension deformation. The aluminum-foam-filled corrugated plates made of different aluminum alloy plates with different strengths all show similar mechanical properties. The 3003 aluminum alloy plate with good formability, high corrosion resistance, and good weldability is suitable for face plates and corrugated plates.
