Large-scale preforming – innovative approach in the production of rotor blades

In order to meet the demand for shorter cycle times and higher quality demands of the growing fiber-plastic composite parts (FRP), the Institut für integrierte Produktentwicklung (BIK) of the University of Bremen, the producer of non-crimp fabrics, the SAERTEX GmbH & Co. KG and the rotor blade manufacturer AREVA Blades GmbH developed new manufacturing technologies and automation-enabled materials.
Now it is possible to transform an even deposited pile of textiles to a close-to-final-contour preform with simultaneous quality control. In addition to the preform technology and the resin-injection technology an innovative process chain with low cycle times for the manufacturing of rotor blades can be completed.
