Wire formed from refractory fibers or their precursors and its application for the manufacture of parts made of composite material.

摘要

The wire is formed of long fibers are made of refractory material or a precursor of that - ci, the fibers being arranged parallel to each other, being not twisted, and the holding of the wire is ensured by covering by means of a wire of sacrificial material. For the manufacture of a composite material part, a fiber preform is formed by means of such wires wound, and then the covering yarn is eliminated before densification of the preform by a matrix.
