Near-surface enhancement of honeycomb sandwich structures to improve durability using a hybrid core. |
摘要 |
There is described a combination of a thin upper honeycomb core plus a lower honeycomb core of equal or lower density than the upper core which are united by only a thin light weight interlayer within two outer skins provides a low weight hybrid panel with increased durability when the upper surface is subjected to localized compressive loads. <IMAGE>
