The mix is the key – metering and mixing systems for composites

The wind energy industry is one of the most important customers for composites; at the same time the greatest challenges are made here on the load-bearing capability of the fibre reinforced plastics. Consequently, not only the right raw materials but also their specific blend is a major precondition for use in wind energy.
The industrial production of the enormous blades would be impossible to achieve without the use of technical plastics. Production of the models or the moulds for constructing the rotor shells or the rotor blades as such would be impossible. Even the adhesion of the upper and lower shell would be virtually impossible to achieve.
Two-component metering and mixing systems are required so that the right mixture of epoxy and polyurethane resins as well as modelling and adhesive pastes can be used. A reputable manufacturer of this processing technique is Tartler GmbH from Lützelbach, which will demonstrate its competencies at the COMPOSITES EUROPE trade fair, which will take place from 27 to 29 October 2009 in Stuttgart.
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.
