METHOD FOR MANUFACTURING OF FIBROUS STOCK FOR PRODUCTION OF PARTS FROM COMPOSITE MATERIAL OF CARBON/CARBON TYPE, INCLUDING CERAMIC PARTICLES, AND PRODUCTS PRODUCED BY THIS METHOD

摘要

FIELD: construction.;SUBSTANCE: one or more than one two-dimensional fibrous fabric from carbon fibres or precursors of carbon fibres is impregnated with sol-gel by solution or colloid suspension, providing for possibility of dispersion of discrete ceramic particles to remain on fibrous fabric. Sol-gel solution contains precursor of oxide, and colloid suspension - oxide, selected from the following group: TiO₂, ZrO₂, HfO₂, SiO₂. Fibrous stock is made by means of application of layers formed of two-dimensional fabric made of carbon fibres or precursors of carbon fibres, besides, at least some of layers are at least partially formed of previously impregnated two-dimensional fabric. Layers are connected to each other, and thermal treatment is carried out at the temperature of 1400-1750°C, afterwards fibrous stock is sealed with carbon matrix. In process of thermal treatment particles of oxide are transformed into particles of carbide.;EFFECT: possibility to controllably change concentration of ceramic particles in stock and achievement of required mechanical properties.;14 cl, 5 ex, 11 dwg
