Abstract

A new double-layer lattice structure based on C/SiC composite material is described and being investigated as a means to increase the service temperature of thermal protection structure. The design incorporates a C/SiC double-layer sandwich comprising two pyramidal truss cores. The outer layer of the sandwich structure is the thermal protection layer, which can make the heat redistribute. The internal layer is the insulation layer, which can decrease the temperature of the hot components and increase their reliability. The temperature field of C/SiC lattice thermal protection structures with different geometrical parameters was calculated by the finite element software ANSYS. It is found that the thermal behavior of the double-layer lattice thermal structure is affected by the truss geometry, such as truss length and inclination angle. The thermal protection capacity of C/SiC lattice structure is analyzed and compared with the equivalent solid structure. The results indicated that C/SiC lattice thermal protection structure has lower density and better thermal protection property than the traditional thermal protection structures.
