Elastic moduli along the three major axes of FRP honeycomb core sandwich panel have been calculated using a unit model in 3D-FEM analysis, which was considered from a regular array of honeycomb core in the panel. In the analysis, computing conditions were determined considering compatibility of displacement and equilibrium of force at each node in the unit model keeping continuity at nodes surrounded by those with the same shape and size. Effects of geometric parameters of the unit model such as thickness of the skin and thickness and height of the honeycomb core were evaluated in the study. Almost all the elastic moduli were expressed nearly as liner relations to V_8 (volume of the skin material) and V_c (volume of the core material) in the practical geometrical size of FRP honeycomb core sandwich panel and the deviation from the regular honeycomb core size varied the elastic moduli.
