Development of Encapsulated Dye for Surface Impact Damage Indicator System.

Abstract

Described are the results of two phases of a MIPR program to develop a rapid scan method of detecting the occurrence of foreign-object-damage (FOD) to composite structural components are reported. The Nondestructive Evaluation (NDE) technique is based on an encapsulated dye system within the paint to detect and partially quantify FOD to composite structures. The major accomplishments of this effort were the encapsulation, microencapsule incorporation into the AU polyurethane paint, and initial correlation study of impact damage to impact coating indication. It is the conclusion of the work reported here that the encapsulated damage detection system offers a feasible rapid scan inspection system for carbon-epoxy composites that with further development could play a significant role in the NDE inspection of composite airframe structures.
