FIELD: construction.
SUBSTANCE: when manufacturing products from a composite material, a woven carbonic filler is used as a stock and is impregnated with a composition containing the following components, wt parts: liquid bakelite of grade BZh-3100, organosilicic resin of K-9 grade 100-140, alcohol-acetone mixture 70-100 (with variance of components of not more than 10%), product ADE -3 0.1-0.2. Then drying, hardening, carbonisation, high-temperature treatment are carried out at the temperature of 1800-2000°C to produce a silicon carbide, and then siliconising from gas phase is done.
EFFECT: simplified method to manufacture items and to increase their reliability.
