Composites giving the Airbus wings
August 2nd, 2011 | By Angela in aerospace, Allgemein, Business, Composite production, COMPOSITES Forum, Innovation, Technology | 1 Comment »Airbus is outstripping Boeing. At the world’s largest aviation trade show held recently at Le Bourget near to Paris, the competition between the two largest aircraft makers for the custom of the airlines dominated the news coverage. The Europeans attracted 730 orders (418 of which were binding) to a total value of roughly EUR 50 billion whereas the Americans “merely” posted 142 orders (58 of which binding) worth EUR 15 billion.











Despite the increase in production capacities, the demand for carbon fibres continues to be far greater than the supply. This is evident from the annual market survey by the AVK – Industrievereinigung Verstärkte Kunststoffe e.V. The worldwide capacity in 2007 is estimated to have been 55,000 tons. The applications are multifarious and consist primarily of the sports sector, wind energy, the oil industry, the automobile and transport sector as well as civil engineering. By 2010, an annual increase in the demand for CRP is predicted to be between 14 and 16 per cent. This is due to the development of new applications over and above the previous use. Current new developments can be found, e.g. with hydrogen tanks, although the main application continues to be aviation. Experts think that even though fibre production will experience a double-digit increase as expected, there will continue to be bottlenecks at least in the medium-term.
Block material is usually used for the manufacture of ultra firm, lighter weight carbon composites. This involves the curing of a combination of epoxy resins, micro glass spheres and a curing agent in an autoclave. When curing the pre-impregnated carbon fibres, a composite laminate is produced in the same shape as the original model. This in turn forms the basis for the pertinent carbon component. Epoxy based composite materials have become the norm especially for high speed use, for example in Formula 1.
