摘要
研究了采用轧制复合方法生产不锈钢-3003铝合金蜂窝夹芯板的工艺.结果表明:经过表面清理的面板和芯板,在加热至500～550℃后进行轧制复合,在变形率为25%以上时即可以实现牢固的初结合,面板与芯板间的结合主要依靠'裂口机制';轧制过程中芯板上的圆孔出现了类似于墩粗的情况,为使芯板上孔系能够发挥作用,轧制变形率应当控制在25%～40%之间;经过退火热处理后,夹芯板的抗拉强度、弯曲强度和延伸率等力学性能均达到相关产品标准.
The roll-bonding technology of stainless steel/3003 aluminum alloy honeycomb sandwich panel was studied. The results show that the skin and core plate whose surfaces are cleaned can realize excellent interface bonding when deformation rate exceeds 25% and temperature rangs from 500 to 550℃. The bonding way between both base metal is typically the split mechanism. And round holes of core plate appear bore-out-of-round during the course of roll-bonding. In order to make full use of the holes in the core plate, deformation rate of 25% - 40% is demanded. The tensile strength, flexural strength and elongation of sandwich board all meet the correlative criteria after annealing heat treated.
