The invention belongs to the technical field of composite materials, and particularly relates to a light-weight heterogeneous material and an aging/curing synchronous mold and method for preparing the light-weight heterogeneous material, the light-weight heterogeneous material comprises a plurality of sandwich units which are periodically arranged and have the same specification, the upper end and the lower end of the sandwich unit are respectively glued with the inner surfaces of the upper panel transition layer and the lower panel transition layer, the outer surfaces of the upper panel transition layer and the lower panel transition layer are respectively glued with the inner surfaces of the aluminum alloy upper panel and the aluminum alloy lower panel, and the sandwich unit is of a three-dimensional lattice structure. Compared with the prior art, the aluminum alloy two-stage aging process and prepreg thermocuring are synchronously carried out while the heterogeneous material lightweight sandwich structure
