Abstract:: Based on heat transfer theory with phase change of multilayer board，thermal analysis was imple-mented for metal honeycomb sandwich plate with finite element method ( FEM).The research of phase changeproblem undexr high temperafure load was carried out.The computing results show that honeycomb sandwichplate has good heat insulation performance， the maximum tcmperature difference was more than 450 ℃ bc-tween the inside and outside surface;temperature field distribution in the honeyeomb core layer is not com-pletely identical to the other four layers ; it is different that each layer is influenced by the internal devices ; theouter skin begins to form the solid-liquid phase change after loaded 18s，the outer glue starts to produce solidliquid phase change aiter loaded 11s , and has already large area of gas-liquid phase transition to 14s , damagearea and damage degree are increased continuously. It has been better simulated with FEM that temperatureficld distribution laws，phasc transition failure process and its cvolution of thc complcx strucetures under hightemperature load.
