    Abstract
  • The micro-analysis of a typical and periodical cell selected from the panel was used to calculate the macro-parameters of the sandwich panels. The temperature and st ress fields were analyzed by a three-dimensional finiteelement method and the thermo-mechanical parameters of sandwich panels were given considering heat t ransfer byradiation inner the honeycomb core. The influence of the honeycomb core on heat conductivities , thermal expansioncoefficient s , elasticity properties and bending stiffness of sandwich panels was also investigated. The result s showthat the heat conductivity along the thickness was different from that obtained by t raditional methods , all mechanicalproperties except D12 could use conventional result s to approximate and the effect of the honeycomb core on thermalexpansion could not be neglected.
