Laboratory module for the lecture Konstruktion von Flugzeugstrukturen
Two different types of tests are typically carried out in this laboratory module (2 SWS), using state-of-the-art modern testing and measurement technology. One of these typically relates to the damage tolerance of aircraft structures. In the past, cyclic tests were carried out on metal samples to measure and evaluate crack propagation, and impact tests were carried out on fibre composite samples to determine the residual strength after impact damage. After impact loading on the drop tower and non-destructive ultrasonic testing, the damaged fibre composite samples are subjected to compressive loading (CAI, compression after impact) in order to evaluate the influence of increasing damage on residual strength. Starting in 2026, we will be offering an exciting comparative series of experiments in the field of fibre composite structure joining technology as the second experiment, which plays a crucial role in modern aircraft construction: Depending on the focus of the respective semester, we will test and compare the strength and failure behaviour of riveted, bonded and welded thermoplastic fibre composite samples under quasi-static, short-term dynamic or fatigue loading. Students will be allowed to fabricate the joints themselves.
The laboratory course involves the independent preparation, execution and evaluation of two experiments in the test hall and in the IFL's materials diagnostics laboratory. A graded report and colloquium on the completed laboratory experiments are included in the final grade along with the exam result.
The laboratory dates can be found in the Stud.IP event.
