The invention discloses a lightweight/bearing/ablation-resistant/heat-insulating/wave-absorbing multifunctional composite structure based on a superstructure. The lightweight/bearing/ablation-resistant/heat-insulating/wave-absorbing multifunctional composite structure comprises a lower panel, an upper panel, a corrugated support plate, a wave-absorbing metasurface layer, an ultrahigh-temperature ceramic coating and a ceramic aerogel filler. The corrugated supporting plate is located between the lower panel and the upper panel, the bottom of the corrugated supporting plate is fixedly connected with the upper surface of the lower panel, and the top of the corrugated supporting plate is fixedly connected with the lower surface of the upper panel. The wave-absorbing metasurface layers are distributed on the surface of the corrugated supporting plate in a periodic array mode, and the lower surface of the upper panel is also provided with the wave-absorbing metasurface layers which are distributed in the periodic array mode. And the superhigh temperature ceramic coating is coated on the upper surface of the upper panel. The space between the lower panel and the upper panel is filled with the ceramic aerogel filler. The structure has the advantages of integration of multiple functions of stealth/thermal protection, light weight, high bearing strength and the like, and a new way can be provided for integration of bearing, stealth and thermal protection of hypersonic flight vehicle components.
