Assessment of self-healing capabilities, a route towards standardization

ID No : ACM-01 ABSTRACT In the last decade, an increasing attention has been given to the development of repairing capabilities in materials, with an emphasis in specific strategies that can promote self-healing, with or without external triggers. Self-healing has opened several new possibilities, especially in applications where long-term reliability is demanded and either maintenance or replace of these materials is difficult to perform. Depending on the material class, different approaches in order to achieve selfhealing, can be adopted. This led to distinct evaluation methods of the self-healing efficiency, depending on the material and its final use. One of the new challenges in self-repairing materials lays in the establishment of a common testing procedure for different materials classes, such as ceramics, concrete, polymers and composites. Normalized procedures can conduct to a standardization of the healing evaluation, which will set a common ground towards a better understanding of the concept and its quantification. The assessment of self-healing capabilities is one of the major goals in the SHeMat project. SHeMat is a Training Network for Self-Healing Materials funded within the scope of the Seventh Framework Programme by the European Commission's Marie Curie programme. The focus of this work will be the development of a standard procedure and its applicability to the specific materials developed within the project. The comparative analysis of the results will act as a support to establish a common base for the definition of self-healing as a quantifiable characteristic. This discussion covers the work that has been conducted so far in the SHeMat project and possible future directions.In the last decade, an increasing attention has been given to the development of repairing capabilities in materials, with an emphasis in specific strategies that can promote self-healing, with or without external triggers.
