Claim:
1. A process for producing a carbon fibre, comprising the following steps: a) mixing 0.01-2 parts by weight of a carbon nanotube and 100 parts by weight of a solvent, and ultrasonic processing for 1.5-3 hrs with an ultrasonic cell disrupter at 300 w-600 w to obtain a mixture; b) adding 0.01-5 parts by weight of a polymer thickener to the mixture from step a) followed by ultrasonic processing for 1-2 hrs with an ultrasonic cell disrupter at 300 w-600 w to obtain another mixture; c) forming a coating of 100-300 nm on pre-oxidized fibre with the mixture obtained from step b), followed by carbonizing, to obtain the carbon fibre.
