Abstract

The development and production of carbon fiber reinforced plastic (CFRP) exterior parts with Class-A surface finish in the automotive industry comes with challenges. Next to the structural design of the components, the surface quality as well as the joining technique to the body-in-white and the Mercedes-AMG specific factory integration into the worldwide production lines of the Daimler AG need to be considered.
The aim of the thesis was to experimentally qualify an in-house developed open-mold polyurethane injection bonding technology to produce and bond a subframe structure in one process to the inside of a modular CFRP roof with Class-A surface finish. The qualification was done by means of experimental material and process verification and in close collaboration with the adhesives team at Daimler AG Sindelfingen.
