Abstract
1,238,308. Carbon fibre treatment COURTAULDS Ltd. 14 Nov., 1968 [14 Aug., 1967], No. 37213/67. Heading C1A. [Also in Division C3] Carbon fibres produced by heating fibrous organic materials are improved by treatment with liquid oxidizing agents. The examples of organic materials specified are cellulose, polyamide, polyester and polyacrylonitrile fibres. In the example polyacrylonitrile filaments are treated with HOC1 containing about 14% available chlorine at pH 8 for 3 hours. Alternative oxidizing agents are cone. nitric acid, mixed nitric and sulphuric acids, perchloric acid, phosphoric acid, hydrogen peroxide, bromine ferric chloride and potassium perchlorate with or without nitric acid. The treated fibres may be incorporated into a synthetic resin matrix (see Division C3).
