FIELD: chemistry.
SUBSTANCE: method is described that includes heating hydratecellulose fibres, examining their thermochemical transformation into carbon fibres, and determining physical and mechanical properties, characterized in that the test HC-fibres are subjected to derivatographic analysis in comparison with a similar analysis of the HC-sample of the reference fibre, evaluating the obtained data, selecting the test HC-fibres nearest to the reference HC-fibre during pyrolysis is carried out, then the selected HC-fibre is tested for the process of the thermochemical transformation into a carbon fibre using the technology of producing a reference sample and the technology mode for producing the carbon fibre of the test fibre is corrected.
EFFECT: high efficiency of selective evaluation and process optimisation in the production of carbon fibres based on new hydrate-cellulose raw materials.
