Nowadays, honeycomb sandwich panle is widely used in the field of aircraft and spacecraft, due to its light weight, high strength and good impact resistance. So the stability and buckling behavior of the structure are crucially important. In the present work, two type aluminum honeycomb sandwich panles were manufactured by a new manufacturing method (i.e. a press and folding process). To evaluate the structural failure of the panle, the three-point bending test was carried out, and found that the face sheets and the honeycomb core were splited open under a local load, but the panle has not been completely failure. In addition, the buckling behavior of the panle was implemented with finite element analysis (FEA).
