Abstract :
Rayon fibres were pyrolysed under inert gas flows up to 1200 °C. Changes in the mechanical properties of the fibres at various stages of the thermal treatment were studied and correlated with structural analyses of the char by CP/MAS 13C NMR and DRIFT spectroscopies. The force/displacement curve of fibres pyrolysed at 500 °C is non-linear but reversible within the deformation, which is approximately 10% at ultimate failure.
