Abstract: There is provided a system, a method, and a thermochromatic witness assembly to monitor a thermal environment of a composite structure. The thermochromatic witness assembly has a polymeric material and one or more thermochromatic probes mixed into the polymeric material to form a thermochromatic probe mixture. The thermochromatic probe mixture is applied to a transparent polymeric film, or is formed into the transparent polymeric film with a pressure sensitive adhesive (PSA) applied thereto, thus forming the thermochromatic witness assembly in a form of a thermochromatic applique. The thermochromatic applique is configured to be applied directly and continuously to a surface of the composite structure. The thermochromatic applique is further configured to monitor the thermal environment of the composite structure by detecting one or more temperatures and one or more times the surface of the composite structure is exposed to the thermal environment.
