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.

1-11. (canceled)
A method for making a fiber-reinforced polymer composite, the method comprising:
- contacting a fiber in a first solution, thereby generating an intermediate fiber, the intermediate fiber including a monolayer on at least a portion of an outer surface of the fiber;
- rising the intermediate fiber in a second solution and then drying the rinsed intermediate fiber, thereby generating dried intermediate fiber;
- contacting the dried intermediate fiber in a third solution, thereby generating a second intermediate fiber;
- rinsing the second intermediate fiber in a fourth solution;
- drying the rinsed second intermediate fiber, thereby generating functionalized fiber, wherein the functionalized fiber is sensitive to ultraviolet light;
- combining the functionalized fiber with a polymer matrix material;
- curing the combined functionalized fiber and polymer matrix material, thereby generating a cured composite material;
- and
- irradiating the cured composite material with a light source, thereby generating the fiber-reinforced polymer composite.
