泡沫铝填充波纹夹芯板面外压缩的三维效应

3D Effect of Sandwich Panels with Aluminum-Foam-Filled Corrugated Plates Under Out-of-Plane Compression

研究了闭孔泡沫铝板、3种空心波纹铝板和3种用环氧树脂粘接而成的闭孔泡沫铝填充波纹铝板的平面外压缩性能。泡沫填充波纹铝板不仅能显著提高抗压强度和吸能能力,而且力学性能更加稳定。泡沫填充波纹板具有明显的三维压缩效果。铝合金板材强度越小,三维延伸变形越明显。由3种不同强度的铝合金板制成的泡沫铝填充波纹板具有相似的力学性能。成形性好、耐腐蚀性高、可焊性好的3003铝合金板非常适合作为面板和波纹板。

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.
