摘要
以孔隙为特征的超轻型金属结构具有特殊的物理和机械性能组合,如轻质和高比强度的结合,正成为当今研究的热点。轻量化的需求使得具有更高比强度、比刚度的泡沫铝成为发展的重点。文中针对闭孔泡沫铝夹层结构进行应用技术研究,解决了采用该结构代替铝合金7075制造某天线安装板的技术问题,在满足力学性能的情况下实现了天线安装板减重54%。
Ultra-light-weight sandwich metal structure characterized by cells has special combination of physial property and mechanical property,such as the combination of light-weight and high specific strength. It is becoming the hotspot of current research. The requirement of light-weight makes the aluminum foam with higher specific strength and specific stiffness the important development direction. In this paper,the application technologies of sandwich structure with closed-cell aluminium foam are studied. The manufacture solution of the fixing-board of an antenna using the sandwich structure as a replacement of aluminium alloy 7075 is obtained.54% weight reduction of the fixing-board is realized while satisfying its mechanical property.
