This article proposes a 316 stainless steel lattice lightweight sandwich structure as a potential application manufacturing for thermal protection systems. First, establish low-relative-density BCC and FCC lattice structures to meet the design requirements of lightweight. Secondly, use the transient thermal analysis and steady-state thermal analysis modules of the finite element software to analyze the heat transfer characteristics of the structure. Through the distribution and change trend of the temperature field of the structure at different temperatures, the thermal insulation effect is analyzed and the heat transfer process of different structures is compared to obtain a relatively good lattice structure, and obtained BCC structure has a model lightweight design and high thermal insulation effect.
