Cover Story: Metal–polymer composite components used in the automotive industry need to be recycled. Therefore, the joints between polymers and metals have to be broken. The joining mechanism and the applied stress influences the success of the material separation. Crushing demonstrator components in a mill using a hammer and an impact rotor shows that force-fit joints are better for the complete separation of polymers and metals. The more complex the form-fit joint, the more difficult it is to separate the materials completely. Other factors influencing the success of crushing are the polymers used and the crushing temperature. View this paper
