摘要：

The feasibility of using so-called Bragg sensors for the continuous monitoring of the mechanical behaviour of composite structural elements is studied. The advantages and disadvantages of optical fibre sensors are given. After a brief description of the working principle of Bragg sensors, their inherent advantages and limitations are discussed. Fibre optic sensors are successfully embedded into several composite specimens. Both static and quasi-static bending tests are performed on small and larger plates. The frequency of a vibrating laminate is measured and related to its global damage state. Pressure vessels are subjected to a wide range of load cycles. Results are reported for a number of tests.
