Performance Comparison of the Hexagon and the Overexpanded Honeycomb

Abstract:

With the development of radar-detecting technology, stealth technology is important for military weapons and equipment. As a typical structural stealth material, wave absorption honeycomb has a wide range of application prospects and research value. The light and high absorption wave absorption honeycomb that uses electromagnetic-modified aramid paper as a raw material has the advantages of light density and good absorption performance, making it suitable for the lightweight requirements of the new equipment. Here, the electromagnetic-modified aramid was the raw material of the honeycomb. The hexagon honeycomb and overexpanded honeycomb were prepared. We also analyzed the influence of the cell shapes on the honeycomb properties. The results showed that cell shapes had little effect on the plane compression and shear performance of L. The overexpanded honeycomb’s L and W shear performance was basically the same. The hexagon and overexpanded honeycomb have good electromagnetic wave absorption performance in 1 GHz ~ 18 GHz frequency band.
