    Abstract

    Creep tests were performed with carbon fibre-bundles (Toho Tenax, HTA 5131) in a temperature range from 1500 to 1800 °C. The fibre-bundles were electrically heated in vacuum (pressure 10-4 mbar) and tensile load was applied in a hydraulic testing machine. The creep parameters were obtained from varying temperature and loading conditions. Accompanying structural investigations were performed with X-rays (SAXS and WAXD). An increasing orientation of the graphene planes along the fibre (and thus the loading axis) could be observed with increasing temperature and load. No structural change and no creep, however, was observed for carbon fibres stabilized by an appropriate heat treatment. Œ 2006 Blackwell Publishing Ltd.
