The invention discloses a multi-gradient heat-proof bearing integrated composite material which is composed of an upper panel, a bridge-shaped web, a sandwich heat insulation material and a lower panel, the upper plane of the bridge-shaped web is connected with the upper panel through a secondary cementing process, and the footing plane of the bridge-shaped web is vertically connected with the lower panel through a cementing co-curing process; the bridge type web is of a multi-gradient composite bridge structure, an ablation-resistant structure layer, a heat insulation structure layer and a bearing structure layer are laid from top to bottom to form a preformed body through prepreg, and the ablation-resistant structure layer and the heat insulation structure layer are distributed in a gradually-changing and gradually-decreasing structure from top to bottom. The tail end of the bottom of the ablation-resistant structural layer is paved on the heat insulation structural layer, the tail end of the bottom of the heat insulation structural layer is paved on the bearing structural layer, and the tail end of the bearing structural layer is in contact connection with the lower panel at 90 degrees. The material is light in weight and good in bearing and heat insulation performance.
