The development of innovative and low cost glass fibre based sensors for chemicals and new tests and modelling methods for Glass Fibre Reinforced Polymer (GFRP) composites in harsh environments is one of the key themes of the CoACH Europe an Training Network (www.coach-etn.eu). A combination of Evanescent Wave Optical Sensors (EWOSs) and Fibre Bragg Gratings (FBGs) was embedded in epoxy vinyl ester based GRP composites to measure fluid ingress that would result in its degradation under hostile conditions. Samples were subjected to accelerated ageing in the form of single sided exposure to simulated seawater, at 120°C in a pressurised stainless steel vessel. Low cost EWOSs were prepared from a standard multimode glass optical fibre and compared to commercially available FBGs. Both sensors were able to detect the early stage of moisture diffusion into the GRP polymer matrix. Preliminary results and further activities will be discussed. The extremely low cost associated with the production of the sensors in this work will allow them to be applied to the development of accelerated ageing tests for the investigation and comparison of composite materials, an area that is being extensively investigated for the development of new GRPs.

Abstract
The development of innovative and low cost glass fibre based sensors for chemicals and new tests and modelling methods for Glass Fibre Reinforced Polymer (GFRP) composites in harsh environments is one of the key themes of the CoACH Europe an Training Network (www.coach-etn.eu). A combination of Evanescent Wave Optical Sensors (EWOSs) and Fibre Bragg Gratings (FBGs) was embedded in epoxy vinyl ester based GRP composites to measure fluid ingress that would result in its degradation under hostile conditions. Samples were subjected to accelerated ageing in the form of single sided exposure to simulated seawater, at 120°C in a pressurised stainless steel vessel. Low cost EWOSs were prepared from a standard multimode glass optical fibre and compared to commercially available FBGs. Both sensors were able to detect the early stage of moisture diffusion into the GRP polymer matrix. Preliminary results and further activities will be discussed. The extremely low cost associated with the production of the sensors in this work will allow them to be applied to the development of accelerated ageing tests for the investigation and comparison of composite materials, an area that is being extensively investigated for the development of new GRPs. The research leading to these results has received funding from the European Union’s Seventh framework Programme managed by REA-Research Executive Agency in a Marie Curie Action (GlaCERCo GA 264526) and the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 642557 (CoACH, www.coach-etn.eu).Pubblicazioni consigliate
