COMPOSITES EUROPE 2012 Blog

GLENWOOD SPRINGS, CO — 29 June 2010. Fiberforge announces today that Fraunhofer ICT and Fiberforge have started a strategic collaboration on R&D projects for various industries such as, automotive and aerospace. As part of this collaboration, Fraunhofer ICT will be installing a RELAY® Station 2000 at its state-of-the-art thermoplastics research center. This will be the first RELAY Station installation in Europe offering clients the ability to develop and demonstrate the production of thermoplastic advanced composite structures upward of 2 m x 2 m (80 in. x 80 in.) in size on a full-scale production work cell.

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. Read Full Post

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.
