Conclusions
The connection between supermolecular structure of PAN tows and the parameters of the creep process has been discovered, which makes it possible to carry out structural interpretation of viscoelastic properties and can be used in the analysis of technological processes for the preparation of PAN tows.
It has been found that carbon fibres with a high knot strength are obtained from technical PAN tows which are characterized by a more homogeneous and oriented structure, and fibres with a low knot strength are obtained from PAN tows with a heterophase structure and less orientation.
