A composite material is provided that includes laminated layers, an optical fiber,
and a demodulator. The layers define a surface portion generally parallel to the
layers and an edge portion generally perpendicular to the layers. The optical fiber
and demodulator are embedded in the material. The demodulator is optically coupled
to the optical fiber and demodulates light transmitted through the optical fiber.
A method of monitoring the health of a structural member, which includes a composite
material having an optical fiber, is also provided. The method includes demodulating
light from the optical fiber using a demodulator embedded in the composite material.
Also, a signal representative of the demodulated light is received and interpreted
as a condition of the composite material.
