Healing efficiency and dynamic mechanical properties of self-healing epoxy systems

摘要

Several systems to develop selfrepairing epoxy resins have recently been formulated. In this paper the effect of matrix nature and curing cycle on the healing efficiency and dynamic mechanical properties of selfhealing epoxy resins were investigated. We discuss several aspects by transferring selfhealing systems from the laboratory scale to real applications in the aeronautic field, such as the possibility to choose systems with increased glass transition temperature, high storage modulus and high values in the healing functionality under real working conditions.
