The invention provides a multi-scale heat-proof optimization method for a composite material. The multi-scale heat-proof optimization method comprises the following steps: step 1, establishing finite element models of the composite material to be optimized according to design variables, wherein the finite element models comprise a mesoscopic finite element heat transfer analysis model, a macroscopic finite element heat transfer analysis model and a cell body expansion model; step 2, performing mesoscopic heat transfer analysis on the established mesoscopic finite element heat transfer analysis model to obtain equivalent thermophysical parameters; transmitting equivalent thermophysical property parameters obtained through mesoscopic heat transfer analysis into a macroscopic finite element heat transfer analysis model through a cell body expansion model for macroscopic heat transfer analysis; in the heat transfer analysis, optimizing the mesoscopic heat transfer analysis model and the macroscopic heat transfer
