FIELD: chemistry.
SUBSTANCE: invention relates to production of structural articles in additive technologies. Disclosed is a method of producing glazing carbon fibre by applying sizing agent, which is mixture of 2,6-toluylenediamine and 4,4'-dioxydiphenylmethane, on carbon fibre from a solution with a mass concentration of 0.67% in ethyl alcohol, followed by stepped raising of temperature to 85 °C and simultaneous distillation of the solvent and drying in a drying cabinet under vacuum at 83–84 °C.
EFFECT: improved glass-transition temperature of the produced polyether imide compositions.
