Investigating Strain Transfer In Polymer Coated Structures For The Health Monitoring Of Aerospace Vehicles Using Polymer Photonic Waveguides, Graham Wild, Bronwyn Fox, Kevin Magniez, Steven Hinckley, Scott Wade, G Carman

Research outputs 2014 to 2021

In this work, we present the concept of planar polymer photonic waveguides for the health monitoring of aerospace structures. Here a polymer layer is deposited onto the material/structure to be monitored. Within the polymer layer, waveguides are created after deposition. These waveguides can then be used as 'optical fibres' for optical fibre sensing methodologies. In investigating the use of polymer photonic waveguides the question to be answered is: does the strain in the test material transfer to the polymer layer, such that the value to be measured optically is reliable and indicative of the true strain in the test structure? …
