Self-healing of impact-damaged composites.

摘要

Extensive work in the field of self-healing materials has developed several different methodologies and multiple successful systems utilizing the various approaches. Within the paradigm of healing using an embedded microencapsulated healing agent and catalyst the specific materials used can greatly influence the healing efficiency of the system. This work compares the adhesive capabilities of a number of ROMP-capable healing agent candidates. The success of the system at healing Mode I damage in fiber-reinforced composites (FRC) has been demonstrated. This work applies that same self-healing system to the mixed mode failure that occurs from impact damage of a FRC. While the system still allows the necessary steps for self-healing to occur, the damage suffered by this system was more extensive than the repair capabilities of the healing system.
