Applications of fiber optic sensor in aerospace composite materials structural health monitoring and their development are discussed. The applications include Boeing, Airbus, NASA (National Aeronautics and Space Administration) and others. Problems related to fiber optic sensor network applications that need be considered and addressed are pointed out. Prospects of the sensor-based health monitoring technology in the aerospace industry are predicted.
