A framework for assessing self-healing products

Abstract Requirements for safety, reliability and extended life-time has led to the development of new, self-healing materials. In contrast to the literature where “self-healing” is described as a material property, this paper proposes a new approach which deliberates the context of the product and it's restoration of function. Besides providing clarity on “self-healing” products, which is essential for product design or life cycle assessment (LCA), technology readiness level or maturity in transition towards true or autonomous self-healing is also explored, an evaluation that is necessary for enabling healed products to be accepted and certified in applications.
