Fibre-reinforced thermoplastics are increasingly coming to the fore for automotive applications. Already in use for mounting parts like the diffuser frame in BMW i8 or the infotainment carrier in Audi A6 the next step is to employ this material in structural applications. Since car body structures are passing through a conventional automotive process chain and rearrangements of or adjustments to it include additional costs, it is the OEM’s intention not to make changes. Due to this fact fibre-reinforced thermoplastics must be capable of running through the existing automotive process chain including distinct influences. As little is known about the correlation of cathodic dip painting and the properties of fibre-reinforced thermoplastics, the author’s ambition is to gain an elementary understanding of it. Therefore tensile tests are conducted before and after the cathodic dip painting process with different fibre-reinforced thermoplastics. The results show that while the fibre-dominated properties are not influenced by the cathodic dip painting process the matrix-dominated properties increase.
