Joining (embroidery) of RFP

The aim of the project was to develop a demonstrator of an embroidery or sewing machine that is able to connect consolidated areas. In order to maintain the tensile strength of the materials, the connection should be created without destroying the reinforcing fibres. At the same time, the connection should be permanent. This was to be realised by testing sewing technology as a joining process on consolidated fibre-reinforced plastics and comparing the strength of the connection achieved with other joining technologies. Particular attention should be paid to the impact the connection hole, the connecting thread, the type of sewing and subsequent welding have on the connection’s stability.
