The invention discloses a thermal protection device and a reentry vehicle. The thermal protection device comprises a rigid or flexible thermal insulation layer made of fibers. One side of the thermalinsulation layer is connected with a heat protection cover plate, and the heat protection cover plate is made of a Cf/SiC material. The characteristics of oxidation resistance, low ablation, scouringresistance and high radiance of the Cf/SiC material are combined with the characteristics of low thermal conductivity and low density of the thermal insulation material, the thermal protection layer composite material with high use temperature can bear the high temperature of 1,760 DEG C, and a supporting structure can bear the temperature and stress conditions of 1,350-1,600 DEG C.

    本发明公开了一种热防护装置和再入飞行器,热防护装置包括由纤维制成的刚性或柔性的隔热层;所述隔热层的一侧连接有防热盖板,所述防热盖板由Cf/SiC材料制备而成。C/SiC材料抗氧化、低烧蚀、抗冲刷、高辐射率的特点结合隔热材料低导热、低密度的特点,使用温度高、防热层复合材料可承受l760℃的高温,支撑结构可承受I350~1600℃的温度和应力条件。
