The invention relates to a light composite material heat insulation tile for spaceflight, which structurally comprises four layers of materials, namely a carbon fiber composite material substrate layer, a heat insulation layer, a ceramizable ablative layer and a surface mechanical property strengthening and infrared radiation function strengthening material layer in sequence from the joint with the surface of a spacecraft. The manufacturing process is simple, the material cost is low, the used carbon fiber composite material substrate can be reused, and the thermal protection cost of the commercial spacecraft can be greatly reduced.
本发明涉及一种航天用轻质复合材料隔热瓦,其结构包括四层材料,从与航天器表面结合处开始,分别为依次为:碳纤维复合材料基底层、隔热层、可陶瓷化烧蚀层、表面机械性能强化与红外辐射功能强化材料层。本发明的制造工艺简单、材料成本低廉,所使用的碳纤维复合材料基底可以重复利用,可以大大降低商用航天器的热防护成本。
