This useful guide provides a practical approach to making carbon fibers and their composites. The book begins with a brief history of the development of carbon fiber, defining the terminology for all forms of solid carbon and the properties for elemental carbon and its allotropic forms. Various precursors for carbon fibers, corresponding surface treatments and sizes for various types of carbon fiber available on the world market are presented. The book gives an excellent overview of the chemical and physical properties of carbon fibers and their composites. Common test and analysis methods for verifying these properties are also presented. In several chapters, typical processing processes for carbon fibers with dry and also impregnated semi-finished products in application areas such as aerospace, wind industry and automotive up to the construction industry are presented. The advantages and disadvantages of various manufacturing processes are shown based on application examples. Considerations regarding carbon fiber recycling and sustainability (environmental footprint) as well as new developments in the field of carbon fiber production should support the reader in the selection and understanding of material, process and design in order to be able to implement them successfully.


Hauke Lengsfeld:
After studying chemistry in Kiel and completing his doctorate at the chair for polymer materials at the University of Bayreuth (Prof. Dr.-Ing. Altstädt), Dr.-Ing. Hauke ​​Lengsfeld at Airbus Operations GmbH as a material and process expert in the production of large CFRP components. As head of technical marketing and sales at Saertex Stade GmbH, he was involved in the development of CFRP components for the A350XWB. At Hexcel Composites GmbH he worked as Technical Support Manager for Central Europe. During this time, he produced his first book on the processing of prepregs in close collaboration with other authors. Since 2018 he has been working as a division manager for the development of epoxy products at Schill + Seilacher "Struktol" GmbH. Dr.-Ing.|||After studying chemical engineering (specialization in molecular and structural product design) at Otto von Guericke University Magdeburg, Dr.-Ing. Hendrik Mainka at the Bremen Fiber Institute at the University of Bremen (Prof. Dr. Axel Herrmann) in the field of production technology. From 2011 to mid-2015, Dr.-Ing. Hendrik Mainka in Group Research at Volkswagen AG and was responsible for the FA Alternative Fiber Reinforcements in the Materials and Manufacturing Processes department. In August 2015, Dr.-Ing. Hendrik Mainka joined the Volkswagen Group of America and heads the Product Innovation department at the North American Engineering & Planning Center. Dr.-Ing. Hendrik Mainka also completed a one-year research stay at the Oak Ridge National Laboratory (Material Science and Technology Division, Subdivision Carbon and Composites) in the USA.|||After studying physics and completing his doctorate, Volker Altstädt worked for eight years in polymer research with Prof. Gottfried W. Ehrenstein at the Institute for Materials Technology in Kassel (1987), most recently as a group leader in the polymer physics department. From 1995 he was professor at the Technical University of Hamburg-Harburg. In addition, from 1998 he took over the management of the plastics and composites division. In 2000, Volker Altstädt moved to the University of Bayreuth, where he became head of the chair for polymer materials at the Faculty of Engineering. In parallel to this function, Volker Altstädt is managing director of Neue materials Bayreuth GmbH, a non-university state research institution of the Free State of Bavaria,
