INTERMEDIATE MATERIAL FOR TRANSFORMING MEDIUM CERAMIC PRECURSORS FOR STORING CERAMIC PRECURSORS, PROCESS FOR THE PRODUCTION THEREOF, TRANSFORMATION OF INTERMEDIATE MATERIAL

摘要

Intermediate material based on ceramic precursor consisting of continuous fibers impregnated with a matrix of ceramic precursor, the assembly being continuously sheathed with a flexible plastic resin. /P P This intermediate material is prepared by sheathing by means of flexible plastic resin of fibers previously passed through a fluid precursor. /P P This technique makes it possible to store the precursor in the absence of air before use, and to transform directly by heating to at least 800 degree (s) C in ceramic a preform prepared using this sheathed precursor.
