摘要：
The experiment and simulation investigations on out-plane compressive characteristics of FRP sandwich panel were conducted. The results show that two deformation stages are elastic deformation and fracture stages in out-plane compressive deformation. The yielding mode deformation as t1/h which is very big, while the buckling mode deformation as t1/h which is very small. The part 2 in the honeycomb core is main bearing part for sandwich panel, and the part 2 is supported by the part 1 and part 3 in the honeycomb core, while the honeycomb core is supported by the panel. So, the cell wall thickness of part 2 has the most significant influence on the compressive strength, and the influence by the cell wall side length of honeycomb core is the secondary, while the influence by the cell wall thickness of part 1 and part 3 in honeycomb core and the thickness of panel is the weakest. When the honeycomb core height is fixed, the compressive strength of FRP sandwich panel gradually increases along with honeycomb core layers increase. © 2017, Journal of Materials Engineering.
