| Abstract: | Three samples of polyacrylonitrile fibres used for production of carbon fibres were investigated by x-ray diffraction, differential
scanning calorimetry, and thermogravimetry. It was found that spinning of polyacrylonitrile fibre with the thiocyanate method
ensures a smaller crystallite size, while the composition of the copolymer affects the thermogravimetric parameters. |
