Beschreibung
Zusammenfassung:	The invention relates to a carbon fibre prepared from cellulose, which has good tensile mechanical properties, in particular a Young's modulus greater than or equal to 85 GPa and a breaking stress greater than or equal to 1800 MPa, and also a hydrostatic density of between 1.3 and 1.65 g/m3. A process for preparing such a fibre comprises heat treatment of said fibre at a moderate temperature not exceeding 1500°C, at the same time as considerable stretching of said fibre.
