Ablator compositions |
摘要 |
The invention relates to an ablator composition for providing ablation protection after cure thereof. The. ablator composition includes the components of: (A) 100 parts by weight of a silicone elastomer composition which is curable to a silicone elastomer by addition reaction; (B) 50-200 parts by weight of an amorphous silica having an average diameter from 0.1 to 100 mu m; and (C) 1-15 parts by weight of a first fiber having an average length from 0.5 to 6 mm in a longitudinal direction thereof and an average diameter from 1 to 20 mu m. The first fiber is at least one of a carbon fiber and a synthetic quartz fiber. An ablating material prepared by curing the ablator composition is superior in heat insulation and substantially low in ablation rate, and thus protects a spacecraft or the like from a high temperature gas, for a long time.
