The technologically closed process chain of the Institute within the area of fiber reinforced composites is the basis for the research and development of new design methods for high lift devices. However the unique selling proposition of the research range became from the conversion of the authority to thermoplastic and thermo set materials, the advancement of the processing and joining techniques and the know-how of high velocity impact behavior of CFRP structures in prototypes and in original scales. The innovation in the design method is based essentially on the load-specific local combination of homogeneous and fiber reinforced thermoplastics and the optimization of the FOD- and/or bird strike behavior of the component by the stacking special plies into the material. Numeric tools and methods, which are developed and verified in the Institute, are of crucial importance. New developed, material-specific joining techniques lead to reduction of working procedures. An aim is it to reduce the production costs to a minimum. Most prominent examples of the new design method compiled at the Institute are a vertical stabilizer for a generic combat aircraft and a section of a slat made out of fiber reinforced thermoplastic composite.
