Claim Text:
1. A reinforcing fiber ribbon for reinforcing a transparent matrix composite, the reinforcing fiber ribbon comprising: a transparent portion having a refractive index; a first flattened surface through which light incident in a first direction enters the transparent portion of the fiber and refracts, thereby changing its direction; a second flattened surface, differing from the first flattened surface, through which light exits the transparent portion of the fiber ribbon and refracts a second time thereby changing its direction a second time to the first direction; and opaque edge portions extending between and connecting the first flattened surface and the second flattened surface, wherein the fiber ribbon has an elongated cross-section and the transparent portion forms the longer dimension thereof; and wherein light entering the first flattened surface is prevented from passing through the opaque edge portions.
