Abstract

The relative merits of a number of fiber optic sensors are compared in terms of their suitability for use in smart structures. It is shown that the Michelson fiber optic sensor is suitable for detecting damage-induced acoustic emission within composites in the laboratory and for testing the concept of an optical strain rosette. However, its limited application in terms of smart structures has led to the development of a Fabry-Perot fiber optic sensor for strain sensing within composite structures. A damage assessment system for composite material structures based on embedded optical fibers has been developed and fabricated within the composite leading edge of an aircraft. The results clearly support the concept of structurally integrated fiber optic damage assessment systems for composites.
