Integrated Sensing, Monitoring and Healing of Composite Systems
The ability of a material to recover its nominal properties through self-healing is gaininginterest in the research community. However, current approaches remain predominantly passive incounteracting the effect of damage. As a result, healing only begins when the material has occurreddamage and typically there is a mismatch between the healing and damage rate. For applications suchas aircraft, where there is a thin line between functionality and non-functionality, these limitations maybe inherently restrictive. A self-healing system that combines a prognosis unit to predict and estimatethe failure rate and an active self-healing system that matches the healing rate to the estimated failurerate using a feedback loop, has the potential to overcome these limitations. In this paper we proposesuch a system and present results for its application to composite materials.
