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.

摘要： An end-burning grain of a solid gas-generating composition which may be a propellant for use in rocket motors, in which an elongate metal heat conductor is embedded to increase mass burning rate by the effect of heat transferred from the hot combustion gas to the unburned gas-generating composition through the heat conductor. The improvement resides in that the heat conductor is constituted of a plurality of relatively thin wires which are loosely twisted together. This heat conductor can produce greater extent of increase in the burning rate and has a mechanical strength sufficient for embedding in a practical grain.
