Abstract

Composite-composite or composite-metal bonded joints, are used in various industries and applications. The difficulty with any bonded construction with regard to structural integrity monitoring is, of course, that the bonded structure cannot be disassembled easily. Various NDE (non-destructive evaluation) techniques have been suggested to monitor bonded joints based on ultrasonic, acoustic, thermal and backface strain measurements [e.g. 1-3]. Among NDE optical techniques suggested, the use of uniform fibre Bragg grating (FBG) sensors has been the most widely favoured, with a number of demonstrations available in the literature for monitoring bonded joints, repairs and structures [e.g. 4-6]. In addition, chirped fibre Bragg grating (CFBG) sensors have been investigated more recently for damage monitoring in composite materials, bonded joints and sandwich structures (e.g. [7-11]).
