Abstract
A method of testing composite materials for structural damage. A plurality of optical fibers are embedded in the composite material in predetermined patterns and light is introduced into one end of each fiber. A computer-connected optical receiver disposed in light-collecting relation to the opposite end of each fiber senses the presence or absence of light emerging therefrom. Detection by the computer that light has passed through any given fiber indicates that the composite is free of damage in the area along the extent of that fiber. If light is not detected emerging from any given fiber, this indicates that damage has occurred in that part of the composite structure within which that particular fiber is embedded.
