Construction CFRP Repair

Increasing production figures of FRP-based cars and the manufacturers’ variety of individual components require a state of the art automated repair processes. Together with 60 industry partners, the RWTH Aachen University is currently working on a project for an integrated repair strategy. It is based on standardised damage detection, a database-oriented damage assessment as well as the individualised production of repair patches conforming to Industry 4.0 guidelines.

Current situation

Carbon-fibre reinforced plastics (CFRP) offer a significant contribution to an increase in energy efficiency of cars. It follows, that the everyday use of CFRP-part containing cars results in a larger amount of damaged CFRP parts which can’t be repaired by using standard methods common in car body construction. In addition, it is difficult to detect damages in CFRP structures in comparison to metal parts. Damages can negatively affect mechanical properties of CFRP parts without showing any indication on...
