Abstract
1383863 Forming a carbon body SIGRI ELEKTROGRAPHIT GmbH 7 Feb 1973 [12 Feb 1972] 6118/73 Heading C1A A reinforced composite body is formed by providing a body of reinforcing fibres in a carbonizable resin matrix and curing and carbonizing the resin by heating in an inert atmosphere at a temperature of at least 800‹ C., the reinforcing fibres being formed from a non- cellulosic polymer which undergoes cross linking when treated with an oxidizing agent, said fibres having been so oxidized to convert them to a thermally stable condition and then having been heated in an inert atmosphere to a temperature of from 300‹ to 500‹ C. for from 5 to 10 mins. until the fibres achieve a state in which during carbonization of the cured resin matrix they shrink by an amount of from 6% to 10%. This shrinkage is approximately the same as that suffered by the matrix during carbonization. The fibres may be formed from a homo polymer or copolymer of acrylonitrile, e.g. acrylonitrile with up to 15 mole per cent of one or more of methacrylate, vinyl chloride, vinylidene chloride, and styrene. The fibres may be oxidized by heating in an air stream, or by reacting with a halogen or peroxy compound, the oxidation of the fibres being effected at from 180‹ to 300‹ C. If desired before being oxidized the fibres may be contacted with a Lewis acid, e.g. the tetrachloride of Ti or Sn. The Lewis acid may be complexed with its solvent. A nitrogen atmosphere may be used to heat the reinforcing fibres. The resin matrix may comprise a phenolic resin, furan, resin, a melamine resin or an epoxy resin. The heat-treated fibres may be covered with resin, laid in a mould, and compressed and the fibres may comprise 30-70% by volume of the body formed with the resin prior to carbonization. The resin matrix may be cured at 120‹ to 180‹ C. under a pressure of 2-10 kp./cm.<SP>2</SP> The carbonized body may be graphitized by heating to 2500‹ to 2800‹ C. in an inert atmosphere.
