Abstract:Using the hexagon instead of the actual honeycomb core, the flat compression strength of sandwich
structure and its relationship with the width to thickness ratio was deduced. Eight kinds of specifications of core flat
compressive strength were evaluated. Statistical results revealed that although there are deviations from the deduced
results, the law is consistent, namely honeycomb sandwich structure of flat compression strength decreases exponen鄄
tially with the increase of core width to thickness ratio d / ts.
