sive wrinkling and corrugation. A disclination model seems to apply to the core of round filaments, the transitions from round to cracked structures imply disclination interactions along the length of the filament. 236. The textile prestretching of PAN-fibres as a controlling parameter for the mechanical properties of the resulting carbon-fibres E. Fitzer and Th. Muller (Inslitut fur Chemische Technik, Universitiit Karlsruhe, BRD). PAN-fibres, obtained from two different sources, having different polymer composition and textile stretch, were oxidized in air at 230°C for optimum time and subsequently carbonized. The influence of textile stretching on the necessary stabilization conditions and on the mechanical properties of the resulting carbon fibres are discussed.
