METHOD OF OBTAINING CARBON-CARBON COMPOSITE MATERIAL Russian patent published in 2014 - IPC C01B31/02 C04B35/52 

FIELD: chemistry.

SUBSTANCE: invention can be used for obtaining heat-protective materials, resistant to the erosion destruction under an impact of high temperatures and pressures. First, the assembly of a rod framework of a cylindrical shape and a pentadirectional reinforcement of carbon fibre is performed with its fixation with a water solution of polyvinyl alcohol. After that, its fixation to the depth of technological overmeasure is carried out by means of a binding agent - the water solution of polyvinyl alcohol, with further uniform crimping in a radial direction on the entire cylindrical surface by the application of compressing forces, after which it is exposed in a crimped state for not less than 1.5-2 hours in water, heated to 60-70°C. After extraction from water the framework is dried, crimping efforts are released and saturation with a carbon matrix is carried out.

EFFECT: obtained carbon-carbon composite material has a dense and homogeneous structure, high erosion resistance and strength under an impact of high temperatures and pressures.
