MOLDING MATERIAL CONTAINING REFRACTORY FIBERS, FOR USE WITHOUT THE FABRICATION OF ABLATABLE PARTS, PROCESS FOR THE FABRICATION THEREOF AND APPLICATIONS THEREOF

摘要

the invention has for its object to usefibrous refractory thermosetting.characterized in that it can be molded by injection.is in the form of a "flock" mainlyfrom 60 to 30% by weight of solid load (40)70% by weight of the thermosetting resin.this material is produced from a moldthe syrup which thermosetting resin catalyzedit introduced the mixing stick toto achieve a homogeneous impregnation of the latter, thenmix the mixture until a flock that isdrying under reduced pressure.application to the manufacture, particularly by injection.composite materials used in the manufacture oftactical missile engines, in particular for nozzlesablatables.
