説明

Stress analysis around a cylindrical insert embedded in the honeycomb sandwich panel is performed and the solution is derived analytically. As a result, it is found that there is a transition layer in the vicinity of the insert where the stresses in the face sheet and the core vary remarcably. Most of the out-of-plane shear force is mainly supported by the face sheet in the transition layer. The strength tests are performed and their results show that the pull-out strength of the insert is independent of the bonding between the core and the insert. It is proved that the potting compound which is usually used to bond them is not necessary. The weight of the honeycomb sandwich panel can be much reduced without using the potting compound.
