The invention provides a heat insulation and bearing integrated cabin structure suitable for a wide-area aircraft, a cabin body comprises a bearing layer, a heat insulation layer and an anti-erosion ablation layer which are sequentially and fixedly connected through bonding layers from inside to outside, end frames used for connection are arranged at the two ends of the cabin body, the bearing layer is used for bearing mechanical loads, and the heat insulation layer is used for bearing the mechanical loads. The erosion and ablation prevention layer is used for preventing erosion and ablation of high-temperature pneumatic heat flow, and the heat insulation layer is used for preventing heat flow of the erosion and ablation prevention layer from being transmitted into the bearing layer. The wall thickness of the cabin body is small, lightweight design is achieved, and meanwhile a better installation space is provided for internal equipment; the honeycomb bearing structure with the zero Poisson ratio does not generate thermal expansion under the heating condition, the thermal matching performance between the honeycomb bearing structure and a thermal insulation material is excellent, interlayer connection is firm, and safety is high; the heat prevention and insulation bearing integrated structure can bear various external loads at the same time, it is ensured that the aerodynamic shape of the aircraft is not changed, and the shape maintaining purpose is achieved.
