The utility model discloses a double-layer corrugated sandwich heat prevention and insulation/bearing integrated thermal protection structure. The integrated thermal protection structure comprises a double-layer corrugated sandwich structure, and the double-layer corrugated sandwich structure comprises an upper panel and a lower panel which are parallel to each other, an upper-layer corrugated sandwich structure and a lower-layer corrugated sandwich structure which are the same in structure, and a middle partition plate connecting the two layers of corrugated sandwich structures. Each of the upper-layer corrugated sandwich structure and the lower-layer corrugated sandwich structure comprises a bearing structure and a heat insulation layer, each bearing structure is provided with a plurality of heat insulation cavities formed by a plurality of webs with parallel central axes at intervals, and the adjacent webs are sequentially connected end to end through connecting plates, so that all the webs are connected into a whole; and the heat insulation cavities are provided with a heat insulation material to form the heat insulation layers. The bearing performance of the corrugated sandwich structure can be improved, meanwhile, the high vibration stability is achieved, the interior of the aircraft structure can be protected against vibration damage, and the defects that in the prior art, a corrugated sandwich structure is low in bearing performance, large in weight and prone to buckling and vibration are overcome.

    一种双层波纹夹芯防隔热/承载一体化热防护结构。包括双层波纹夹芯结构,所述双层波纹夹芯结构包括相互平行的上面板和下面板、结构相同的上层波纹夹芯结构和下层波纹夹芯结构、以及将两层波纹夹芯结构连接的中间隔板,所述上层波纹夹芯结构和下层波纹夹芯结构均包括承载结构和隔热层,所述承载结构由多块中心轴线相互平行的腹板间隔形成多个隔热空腔,相邻腹板的首尾依次通过连接板相互连接使得所有腹板连接为一整体,所述隔热空腔内填充有隔热材料形成隔热层,本发明有助于提高波纹夹芯结构的承载性能,同时具有较强的振动稳定性,能够保护飞行器结构内部不会受到振动破坏,克服现有技术中波纹夹芯结构承载性能低、重量大、易屈曲以及易受振动的缺陷。
