ABSTRACT:
Internal thermal protection for a thruster structure, e.g. an end wall and extender structure of a tactical thruster, is made by preparing a low viscosity elastomer base suitable for being mixed with fibers by means of a mechanical mixer without putting the base into solution, by mixing the elastomer base and the fibers so as to obtain a solid composition in finely divided form suitable for being stored, and by molding the composition in situ in order to obtain the thermal protection directly on the structure to be protected. The viscosity of the elastomer base is less than 1500 Pa.s at 50.degree. C., and it vulcanizes at a temperature greater than 120.degree. C.
