In this work, the organic silicon-based composites were obtained from resorcinol, formaldehyde, TEOS, N-(b-aminoethyl)-g-aminopropyl-trimethoxysilane (AEAPTES) as initial materials for carbon-silica composites producing. The solvent was acetone, those molar ratio to resorcinol varied in following: sample S1 - 1:11; sample S2 - 1:14 and sample S3 - 1:19. Gels were prepared by one-stage method. The silica-organic gels were supper-critical dried. It was shown that the heat treatment of silica-organic gels allows getting silica-organic gels with bigger surface area and total pore volume. The resulting samples were subjected to pyrolysis in a nitrogen atmosphere at 700 °C for 3 hours. It should be noted that in the pyrolysis of samples of significant shrinkage occurred. The loss of volume was 30-40 %. The textural parameters of carbon-organic composites influence on the textural parameters of a carbon?silica aerogel composites.
