Production Joining Techniques

Adhesive bonded joining elements need a high manufacturing effort. Robot based welding onto aerospace CFRP with epoxy based matrix can facilitate a reliable and efficient joining. One prerequisite here is the modification of the CFRP surface with a thermoplastic functional layer.

In aircrafts today a multitude of joining elements are mounted. The program of semifinished products includes cage nuts, stud bolts and cable supports. They are used both for applications with low requirements, like the attachment of heat insulation, and for the fixation of complex component assembly to the aircraft structure. The manual adhesive bonding process of the supports is connected with a high manufacturing effort. Several specific work steps are required,shown in Figure 1and the curing time of 8 to 12 h constitutes a significant productivity limiting factor. With the aim to come to a more efficient fastener installation that also shows potential for structural applications the possibility of a...
