Kohlenstoffasern – Herstellung, Eigenschaften, Verwendung

Abstract

Carbon Fibres -Production, Properties and ApplicationsCarbon fibres are primarily regarded as a reinforcing material for resins, but can also be used in metal or carbon matrices. It is anticipated that over the next few years the present inception phase will develop into one of rapid business growth. The expected turnover and price developments, as well as the main fields of application are discussed. A great variety of carbon fibre types are available, whose properties are dictated by differences in the basic structure, yielding an exceptional range of properties from the isotropic low modulus to the high strength, high modulus, highly anisotropic HT and HM carbon fibres. The method of manufacture and the precursor materials are described, in particular the individual processing steps and changes accompanying the pyrolysis of PAN fibres. Future improvements in processing technology and precursor quality, promise a significant increase in the already very high properties level.
