The method solves the problem that when an ultrathin hollow multilayer structure is formed through an existing superplastic forming / diffusion bonding method, the wall thickness is not uniform due to excessive deformation of a core plate. According to the method, the core plate is subjected to large plastic deformation through a pre-reverse expansion method, stress concentration in a material is released, then the protruding part is subjected to plastic deformation through forward expansion, the core plate is subjected to plastic deformation in the reverse expansion stage, stress is more evenly distributed in the forward expansion stage, and therefore the situation that in a local area, the stress concentration in the material is reduced is avoided. And particularly, the phenomena of excessive deformation and thinning of high-strain parts such as fillets and the like are avoided, so that the uniformity of the wall thickness is greatly improved. The method provided by the invention comprises the following steps: (1) pre-forming a core plate and welding isolation ribs; (2) panel forming; (3) combining the core plate and the panel; (4) carrying out reverse expansion on the core plate; and (5) superplastic forming of the core plate.
