METHOD OF PRODUCING CARBON-CARBON COMPOSITE MATERIAL BASED ON CARBON FIBRE FILLER AND CARBON MATRIX Russian patent published in 2015 - IPC C01B31/04 C04B35/83 

FIELD: chemistry.

SUBSTANCE: method of producing carbon composite material based on carbon fibre filler and a carbon matrix includes successive processes for dry layout of a frame based on reinforced filler in the form of fabric made of high-modulus carbon fibre on an holder, mounting the holder with the fabric in a tool for soaking the dry frame by placing in a soaking container and soaking the frame with coal tar and carbonising, followed by soaking the frame with coal tar and carbonising in a sealed container in a high-pressure apparatus, where the pressure transmitting medium used is quartz sand, followed by retrieving workpieces and vacuum graphitisation. The soaking and carbonisation procedures are carried out under pressure and vacuum graphitisation is repeated until a material with density of 1.88-1.91 g/cm³ is obtained.

EFFECT: invention enables to obtain carbon-carbon composite material based on reinforcing filler in the form of fabric made of high-modulus carbon fibre, having improved physical and mechanical properties at minimal costs.
