In this paper the multifunctional sandwich plates with prismatic cores were optimized with respect to their dimensions and mass. The comparison of those plates to plates with honeycomb cores was performed. The two loading directions, longitudinal and transversal, were considered. The plates with prismatic cores have best performances when loaded longitudinally, since the plate characteristics are restricted by buckling of a plate and not of a beam. Plates with the honeycomb cores are more efficient related to weight, than the plates with the prismatic cores for smaller loads. This advantage diminishes with load increase. Based on this analysis a conclusion can be drawn that the sandwich plates with the prismatic cores are the most efficient from the aspect of the optimal mass, for structures which are simultaneously used for load carrying and cooling.
