The results showed that LDA/ Kevlar could decrease the ablation rate of the ablative material. The lowest ablation rate was made when bakelite/ asbestine were added together in a certain proportion.

• 结果表明 ,联二脲、芳纶纤维单独和混合使用都能够降低烧蚀材料的烧蚀率 ,当以 7 5 /0 5的比例混合使用时 ,能够获得最低的烧蚀率 (线烧蚀率和质量烧蚀率分别为 0 1 4 6mm/s和 0 1 5 3g/s)。
