In the re-contouring process of aircraft engine components, the unknown geometry and inhomogeneous material properties of the workpiece are major challenges. For this reason a new repair process chain is supposed which ...

Purpose - The report summarizes the state-of-the-art in aircraft end-of-life strategies. A focus is on latest aircraft types with a high percentage of composite materials. --- Methodology - A literature review is the basic ...

Re-contouring in the repair process of aircraft engine blades and vanes is a crucial task. Highest demands are made on the geometrical accuracy as well as on the machined surface of the part. Complexity rises even more due ...

Due to the rising number of offshore structures all over the world, underwater wet welding has become increasingly relevant, mainly as a repair method. Welding in direct contact with water involves numerous challenges. A ...

This paper describes a laser-based approach for the bonded repair of fiber reinforced plastic (CFRP) parts. According to CFRP's material properties and sensitivity to thermal loads, short pulsed UV laser radiation is ...

Material adapted repair technologies for fiber-reinforced polymers with thermosetting matrix systems are currently characterized by requiring major efforts for repair preparation and accomplishment in all industrial areas ...

Besides welding, high temperature vacuum repair-brazing is already established for nickel-based alloy turbine blades in the aerospace and power plant industries. After the worn turbine blade has been decoated to its substrate ...
