Recent developments in TRP and ARTES have provided significant results in the instrumentation of CFRP structures with optical fibres including Bragg grating sensors, among others. This allows for strain measurement and thermal measurement with a small number of optical fibres, by multiplexing a large amountof sensors.The open questions still present concern mainly the integration of the optical fibres into the composite material and the characterisation of the micromechanicalbehaviour, mainly for strength. This is due to the differing dimensions and stiffness of the structural fibres and the optical fibres. A full characterisation in terms offracture mechanics in the resin system, thermo-elastic compatibility and the coupled stiffness is necessary both for the structure and the sensor system.The activity proposed will profit from the lessons learned in prior lower TRL developments in ARTES 5 (Highly Stable Antenna Technologies, High Performance Tanks with In-Situ Health Monitoring) and TRP (Optical-FibreTemperature Sensor for Structural Health Monitoring: Engineering Model Space Assessment).
