Polymer based elements are frequently subject to high mechanical load. It is well known, that such components can spontaneously break although the mechanical stress has not reached the average maximum load. These fatigue fractures are caused by micro?cracks. A smart approach would be to implement a self?healing function that is able to heal a crack in an early stage and thus avoid crack propagation. Fraunhofer UMSICHT and the Plant Biomechanics Group Freiburg together with co?operation partners develop biomimetic self?healing elastomers having the capability to repair micro?cracks autonomically without any intervention from outside.
