COMPOSITES EUROPE 2012 Blog

Technical principles, trends and innovations – in an international lecture forum, the COMPOSITES EUROPE trade fair will again present specialist lectures on current topics relevant to the industry in 2009. The COMPOSITES Forum will focus on all areas of composite applications.

Topics range from crash-safe materials in the automotive field to sandwich panels in aircraft construction, from growth potential in the construction of wind energy parks to production and machining processes for composites. The programme features a total of 26 lectures and presentations in English and German.

Very light, very sturdy and very expensive. The characteristics of carbon fibres can be briefly described in this way. Consequently, their applications were primarily restricted in the past to aircraft and aerospace as well as to sports equipment. In addition, the so-called monocoque and other components of Formula 1 racing cars are produced using a carbon fibre reinforced plastic. Very large CRP components are employed in the wings and hull of aircraft.

After carbonization of the basic organic raw materials into carbon, the fibres are tensioned and thus achieve higher strengths and rigidities. Further processing takes place as rovings. This involves several thousand fibres which are combined into a strand and are then used as reinforcing fibres in woven fabrics. As low filaments (short fibres) they can be added to polymers. Suitably reinforced plastic components can be produced by means of processing equipment such as extruders or injection moulding machines.

To produce carbon fibre reinforced plastics (CRP), several layers of carbon fibres are embedded in a plastic matrix of epoxy resin, thermoplastics or ceramics. Analogue to glass-fibre reinforced plastics (GRP), press or autoclave processes for prepregs or fibre wrappings are used for production. CRP manual laminates are only employed for small scale runs or for individual production.
