Bio-based Carbon Fibres
Today, life without carbon fibres would be unthinkable. Without them, lightweight construction would be practically impossible. Carbon fibres are found in cars, aircraft, various kinds of sports equipment, but also in batteries. They offer outstanding properties while weighing very little. They are, however, very expensive. Carbon fibres are produced by means of controlled decomposition of oil-based raw materials at high temperatures. The base materials are expensive and their availability is limited. The costs of raw materials could be reduced by using bio-based materials. This would considerably reduce the price of carbon fibres. In the project, wood-based raw materials are used: cellulose fibres are obtained from wood and lignin is generated as a waste product. Wood K plus has been researching cellulose fibres, lignin and carbon materials for several years. The findings are now to be pooled with a view to developing new types of carbon fibre from cellulose and lignin. Additional support is provided by physicists and chemists from the Center for Surface and Nanoanalytics (ZONA) at the JKU.
