Abstract: Mechanical vibrations are serious problems threatening key electronics and components of aerial vehicles under mission. For controlling the vibrations, fibre reinforced polymer composites are promising materials that can provide high damping as well as high strength values depending on their fibre orientations and stack sequences. In this study, Single Lap Joints (SLJs) with glass fibre reinforced adherends were subjected to two different tests; first non-destructive vibrations to measure their damping values, and then quasi-static loadings to assess their structural performance. The focal point was to get the joints with high damping as well as high strength values. For this purpose, the adherends with different fibre orientations and stacking sequencies were manufactured and bonded using a constant adhesive layer of 0.2 mm and an overlap length of 25 mm. It is found the plies with ±450 fibre orientations can contribute to the joint damping considerably depending on their stacking sequencies. The results show it is possible to get high values of damping as well as strength of the joints when using proper parameters. The experimental results are validated using numerical simulations.
