Abstract
A 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.
