Abstract:

This work was dedicated to the investigation of the influence of the effect of carbon nanotubes on the porous and supramolecular structure of precursor polyacrylonitrile (PAN) fibres. A relationship was found between the structure of the fibers produced in a two-stage and three-stage drawing process and the strength properties of those fibres. The structural parameters and properties of PAN fibres modified with carbon nanotubes were compared with corresponding values for the fibres without nanoadditives. It was found that the introduction of carbon nanotubes into the material of PAN fibres increases their deformability at successive stages of drawing to a degree depending on the type of nanotube. This was the main reason for their higher strength properties in comparison with the fibres without a nanoadditive.
