摘要
航天飞行器的工作要求热防护材料具有轻质、高强、抗冲刷的特点,因此宇航材料的发展正在朝着低密度、高性能、耐烧蚀的方向发展。本文对轻质陶瓷隔热瓦、蜂窝增强低密度材料、纳米多孔气凝胶、酚醛树脂基低密度材料、弹性体材料、薄壁树脂基和碳基材料等轻质耐烧蚀热防护材料的发展及现状进行了综述,并对未来发展方向提出了展望。
The property of lightweight,high strength and anti-erosion are requied for spacecraft thermal protection system.Therefore,the development of aerospace materials should be low density,high performance and ablation resistance.The status,progression and future direction for lightweight ablative materials are introduced in this paper.Lightweight ceramic tile,honeycomb reinforced material,nano-porous airgel,phenolic based material,elastomer ablative material and thin-walled resin or carbon based material are included.
