FIELD: chemistry.
SUBSTANCE: invention relates to production of structural articles in additive technologies. Disclosed is a method of producing a finished carbon fibre by applying a finishing agent, which is a mixture of copolyepoxyether based on epichlorohydrin, bis(4-hydroxyphenyl)sulphone and bis(4-hydroxyphenyl)phthalophenone with degree of polymerisation n = 55-60 and 3,4-toluylene diamine, on carbon fibre from a solution with mass concentration of 0.79% in a mixture of propanone-2 and 1,2-dichloroethane, followed by a stepped increase in temperature to 85 °C and simultaneous distillation of solvent and drying in drying cabinet under vacuum at 93±0.5 °C.
EFFECT: shorter duration of the carbon fibre finishing process and improved physical-mechanical and rheological properties of the polymer polyester-ether-ketone composite materials.
