The invention provides a flexible heatproof structure, which comprises a substrate and a plurality of heatproof armor sheets independently arranged on the substrate, wherein the substrate is made of amaterial comprising a shape memory polymer, and the heatproof armor sheets are made of a heatproof ceramic material. The shape memory polymer composite material is used as a substrate, and secondaryshaping and shape recovery are carried out by changing the temperature, so that the problem of being unable to use due to large deformation degree is avoided, and the defect that the existing ceramictile cannot be used at the deformation part of a machine body due to inharmonious deformation of a cold-hot structure is overcome.
本发明提供了一种柔性防热结构,包括基底和多个独立设置在所述基底上的防热甲片,所述基底由包括形状记忆聚合物的材料制成,所述防热甲片由防热陶瓷材料制成。本发明采用形状记忆聚合物复合材料为基底,通过改变温度进行二次赋形及形状回复,避免由于变形程度较大而不能使用的问题,从而克服了现有陶瓷瓦由于冷热结构变形不协调而无法在机身变形处使用的缺陷。
