ABSTRACT:
A process for the manufacture of a fibrous texture for producing a composite material article. The fibrous texture is formed of a yarn comprising discontinuous fibers which are made of a refractory material or a precursor thereof. The discontinuous fibers are disposed parallel to one another, without twist. A covering yarn made of a fugitive material is disposed over the discontinuous fibers to provide integrity to the yarn. The covering yarn is eliminated after formation of the fibrous texture.
