两种含天线复合材料结构的性能对比

CONTRAST ON PERFORMANCES OF TWO COMPOSITES WITH ANTENNAE

复合材料层压板结构和蜂窝夹芯结构是飞机上常用的两种复合材料结构,文中用有限元仿真分析和静力试验,对比天线埋入这两种不同的复合材料结构中在相同外载条件下的力学性能,并测试相同外载条件下这两种结构中天线的电性能。对比结果显示,无论在力学性能上还是介电性能上,蜂窝夹芯结构均比层压板结构具有一定的优势,说明在飞机上将天线埋入蜂窝夹芯结构中具有一定的优势。

Composite laminated plate and honeycomb sandwich are two common composite material structures on airplane.Finite element simulation analysis and static test are applied to contrast the mechanical properties of antennae in the two different composite materials loaded by the same addition loads,also test the electrical function of antennae in the two structures loaded by the same addition loads.The contrast result shows that honeycomb sandwich is better than laminated plate either on mechanical or dielectric properties to some extent,which shows that embedding antenna into honeycomb sandwich is better on airplane to some extent.
