Abstract

The aim of this chapter is to provide an overview of the use of optical fibre sensors for process monitoring and structural integrity assessment of composites. The term 'process monitoring' is used here to describe the various chemical reactions that take place during the cross-linking of thermosetting resins; the term 'curing' is sometimes used to describe the cross-linking process. Apart from monitoring the depletion and formation of specified functional groups during the cross-linking reactions, other parameters of interest include the temperature and residual fabrication strain at specified locations within the preforms. Whilst the focus of this chapter is on thermoset-based composites, the fibre optic sensor systems described here are equally applicable to thermoplastic reinforced composites.
