The paper describes the status of research concerning the flexibilization of contact faces. For an extensive use of systems for flexible car body fixtures it is necessary to develop flexible contact elements to adapt the clamp to diverse part faces. For this different approaches are shown. Especially the approach of using shape-memory material to make contact faces flexible is discussed. Selected experiments were done. This was the first time the shape-memory effect has been shown on voluminous bodies. The material was activated using an induction field via filler. This way of activating voluminous bodies also has been shown for the first time. The usability of shape-memory polymers was demonstrated and the next steps were shown.
