Sensing of repair in chemically self repairing composites

摘要

The question to be answered in this paper is how "does a user determine if a chemical self repair system has succeeded in self repairing damage". Three sensing methods indicated that chemical has been released into damage areas, another four methods were used to indicate that the container or encapsulator had been broken to release repair chemical, but only one method is known to indicate that the chemical reaction of the repair chemical has been accomplished. Many other methods were used to assess the structural or dynamic efficacy of the repairs. These methods of sensing of repair action are detailed with experimental data and results. The novel and ground breaking method of determining repair efficacy receives most emphasis.
