Abstract: Composite material can include a matrix material, a fiber dispersed in the matrix material, and an ultraviolet (UV)-light sensitive mechanophore grafted to a surface of the fiber. A method for making a fiber-reinforced polymer composite can include contacting a fiber in a first solution, rinsing and then drying intermediate fiber, contacting dried fiber in a third solution, rinsing, and then drying the rinsed fiber thereby generating functionalized fiber that is sensitive to ultraviolet light. The functionalized fiber can be combined with a polymer matrix material, cured, and irradiated, thereby generating a fiber-reinforced polymer composite.
