The invention relates to a composite fireproof heat insulation structure which comprises a fireproof upper panel, a fireproof lower panel, a thermal deformation folding structure and expansion type fireproof resin. Wherein the thermal deformation folding structure is distributed between the fireproof upper panel and the fireproof lower panel, the two ends of the thermal deformation folding structure are connected with the fireproof upper panel and the fireproof lower panel correspondingly, and the thermal deformation folding structure is used for deforming after being heated so as to support the fireproof upper panel and the fireproof lower panel to be away from each other; and the expansive type fireproof resin is filled at the peripheral edge of the space between the fireproof upper panel and the fireproof lower panel. The composite fireproof heat insulation structure aims at solving the problem that a metal fireproof plate of an aircraft engine cannot effectively prevent heat from corroding protected parts due to flames.

    本发明涉及一种复合防火隔热结构,包括防火上面板、防火下面板、热变形折叠结构和膨胀型防火树脂;其中,热变形折叠结构分布于防火上面板与防火下面板之间,且其两端分别与防火上面板、防火下面板连接,热变形折叠结构用于在受热后发生变形以支撑防火上面板、防火下面板相互远离;膨胀型防火树脂填充于防火上面板与防火下面板之间的空间的四周边缘。该复合防火隔热结构的目的是解决飞机发动机的金属防火板不能有效阻隔火焰造成的热量向所保护零件的侵蚀的问题。
