ABSTRACT:
A process for the production of a carbon article is provided by which a synthetic organic fibre which is capable of conversion to high strength, high modulus carbon fibre and which has been partially so converted is impregnated with a synthetic organic resin and the resin/fibre impregnate subject to a carbonization treatment in an inert atmosphere at a temperature of at least 1000.degree. C. Preferably the fibre is polyacrylonitrile which has been heated at a temperature of 200.degree. to 250.degree. C in an oxidizing atmosphere. The resin may be a phenol/formaldehyde resin, a polyvinylidene chloride resin or a polyfurfuryl alcohol resin. The process is particularly suited to the production of carbon articles in the form of fibre or rod by drawing the fibre first through the resin to impregnate it and then through a die to form the resin/fibre impregnate.
