HyPatchRepair

In context of lightweight design, increased use of fibre-reinforced plastics is focused by production of parts of airplanes. Actual in aircraft industries the state of the art for repairing skins of airplanes are inspired by repairing technologies for damaged metal parts. Damaged areas are repaired with riveted or glued sheet metal, which means disturbed material structure, reduced aerodynamics and increased weight. This state of the art technology for repairing aerospace structures by riveting is shown in Figure 1. There is a need for a strategy for repairing fibre-reinforced skins of airplanes. This project aims the development of an efficient repairing technology for prospective aerospace structures. For this purpose, a repairing patch with load optimized fibre orientation and a geometry adapted to the damaged area should be integrated into the structure to be repaired…read more
