A molding material containing refractory fibers, which can be used in the production of pieces ablatable, for its manufacture and its applications.

摘要

The invention relates to a molding material containing refractory fibers, characterized in that it can be molded by injection and is present in the form of a "flock" essentially consisting of 60 to 30% by weight of solid fillers of 40 to 70% by weight of thermosetting resin. & br / this molding material is obtained from a syrup of the thermosetting resin, catalyzed in which it is introduced the solid fillers in mixing, so as to produce a homogeneous impregnation of the latter, then the mixture is kneaded until a flock, which is dried under reduced pressure. & br / application to the manufacture, in particular by injection, of composite materials usable in the manufacture of the motors for tactical missiles, in particular of ablatable blast pipes.
