System for detecting exposure of composites of an aircraft to high-temperature

摘要

A system and method of detecting high-temperature exposure of a composite may include applying a composition comprising an adduct suitable for detecting heat and/or mechanical stress in a composite, wherein the adduct reverts to first and second adduct components after exposure of the composition to a temperature of from about 190°C to about 260°C to a surface of the composite; exposing the surface to which the composition has been applied to ultraviolet light; and measuring fluorescence of the composition.
