| 摘要 |
A high-temperature compressible material especially useful in rocket motors to support nozzle ring inserts, the material including a binder which when pyrolyzed leaves a char having substantial strength, and fillers including carbonaceous fillers such as carbon fibers, wools, powders, etc., plus a special filler comprising hollow carbon microspheres which can crush to provide a compressibility to the material when it is confined in a volume-limiting environment, plus other fillers which may be added to obtain special yield characteristics.
