✦ Synopsis

Techniques developed for the measurement of the electrical resistivity and the diamagnetic anisotropy of carbon fibres, in the temperature range 77-300°K are described. Two types of fibres were studied: the Rigilor AC fibres treated at 1100°C and the Rigilor AG fibres treated at 2500°C. The measurements of electrical resistivity performed on single fibres show the presence of some correlation between this property and the cross-sectional area of the fibre. Measurements of diamagnetic susceptibility carried out on bundles of fibres demonstrate a large anisotropy of the fibres. The influence of small neutron irradiation doses on these properties has been studied at room tem-On perature.
