FIELD: textiles, paper.SUBSTANCE: method of producing carbon fiber material comprises treatment of the starting hydrocellulose fiber material in a solution containing 5-7 wt % liquid oligomeric resins corresponding to the general formula: HO{[MeSi(OH)O][MeSiO]}H, where Me is methyl; m and n are integer or fractional numbers: m=1-3, n=3-10 with a molecular weight from 900 to 2400. As the solvent of the oligomeric resins, a composition is used based on compounds of general formula: (SiO)CH, where 3?x?5, y=2x, z=3y. The impregnated hydrocellulose material is dried at a temperature of (150-170)°C, thermally relaxed in the mode of relaxation shrinkage at a temperature of (180-200)°C, the carbonisation is carried out during deformation from (-25)% to (+30)% and finished at a temperature of 700°C, the subsequent high-temperature treatment is carried out at a temperature up to 2500°C at a degree of deformation of (-10)% to (+30)%.EFFECT: improvement of physical and mechanical properties of carbon fiber material in creation of an environmentally safe technological process.5 ex |
