The objective is to develop, manufacture and test TFBG sensors embedded in smart CFRP and GFRP composite structures with dimensions up to 1 m for damage assessment. Diverse material processing methods will be considered for sensor integration into FRPs, such as TFGBs embodied into thermoplastic veils, which are incorporated between layers of pre-pregs or dry fabric before curing. Mechanical tests will be performed to characterise the mechanical performance of TFGBs-based smart composites under tensile, compressive, flexural, interlaminar shear and impact loading. The DC will enhance the modelling capability of TFBG sensors by combining analytical and numerical approaches.
Two experimental SHM studies will be considered in this project in collaboration with partners:
​
material degradation of space composites in a simulated space environment (UV exposure, extreme temperatures);

the influence of local defects (cracks, delamination) on the structural integrity of a composite UAV wing structure during flight conditions.

Verification is by deliverable reports and scientific publications.
