This paper presents an overview of technologies for joining fibre-reinforced polymer composites to thin-walled metal sheets. It covers the areas of welding, bonding with different surface texturing as well as mechanical joining. It analyses the problems arising from the different mechanical, physical properties of metals and composite materials and presents the possibilities of solving them by the application of individual and combined joining technologies.

This paper deals with the investigation of the effect of speed on the form fit joint of dissimilar materials. Thin -walled materials based on steel and aluminium alloy were joined by thermal drilling. The shape and size of the resulting bushing were evaluated. It turned out that the best material combination for joining by flowdrill technology are joints made of steel and aluminum alloy. Aluminum alloy must always be placed in the bottom position. The best parameters of the formed bushing were achieved with the combination of DC-Al or TL-Al materials, at tool speeds of at least 2400 rpm.
