Self Healing Materials : a new concept in materials science Sybrand van der Zwaag, Fundamentals of Advanced Materials group, Faculty of Aerospace Engineering, Technical University Delft. Traditionally man-made construction materials have been developed on the basis of damage prevention concepts. Nature however uses a damage management concept to optimise most of its materials. Translation of the concept has led to the first attempts to make self healing materials. In this presentation some examples of self healing material developments will be presented. While no solution has been found for fusion wall reactor materials, this would be an attractive application and research in this field should be initiated.
