Abstract: |
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. |
Key words: thermal protection;lightweight;high performance;ablative material |
