Abstract
1,236,392. Carbon fibres. COURTAULDS Ltd. 1 Nov., 1968 [4 Aug., 1967], No. 35937/67. Heading C1A. Carbon fibres may be produced by heating organic fibrous materials in an atmosphere of an oxide of nitrogen at 200-350‹ C. and subsequently heating above 1000‹ C. in an inert atmosphere. The former heating may last for 1-12 hours, and the latter may last for “-4 hours. Cellulose, polyamide, polyester or preferably polyacrylonitrile fibres may be used as starting materials. Further heating in an inert atmosphere above 2000‹ C. yields graphitized fibres. The oxides N 2 O, NO and NO 2 may be used.
