Thermal control-wave absorbing integrated composite material, preparation method thereof and spacecraft
The invention provides a thermal control-wave absorbing integrated composite material, a preparation method thereof and a spacecraft, and relates to the technical field of aerospace materials. The thermal control-wave absorption integrated composite material comprises a composite ceramic core and a porous coating layer, the porous coating layer coats the composite ceramic core; the chemical formula of the composite ceramic core is La1-xSrxMnO3/Al2O3, and x is greater than or equal to 0.1 and less than or equal to 0.3; and the porous coating layer comprises Al2O3. Al2O3 is introduced into the composite ceramic core, so that the thermal radiation phase change temperature can be regulated and controlled; al2O3 is used as a coating layer and can be used as a shell component to ensure the strength of the thermal control-wave absorption integrated composite material; the porous structure of the porous coating layer can enable radar waves to be absorbed through multiple times of reflection in holes, and absorption of the thermal control-wave absorption integrated composite material to the radar waves is effectively improved.
本申请提供一种热控‑吸波一体化复合材料及其制备方法和航天器，涉及航空航天材料技术领域。热控‑吸波一体化复合材料包括复合陶瓷内核和多孔包覆层；多孔包覆层包覆复合陶瓷内核；复合陶瓷内核的化学式为La1‑xSrxMnO3/Al2O3，0.1≤x≤0.3；多孔包覆层包括Al2O3。通过将Al2O3引入复合陶瓷内核内，能够对热辐射相变温度进行调控；Al2O3作为包覆层能够作为外壳成分保证热控‑吸波一体化复合材料的强度；该多孔包覆层的多孔结构能够使雷达波在孔洞中经过多次反射被吸收，有效增加热控‑吸波一体化复合材料对雷达波的吸收。
