Summary on Grant Application Form
The proposal is for funding to develop a polymeric optical strain sensor system in the Unit for 'Residual Stress and Damage Characterisation in Materials and Engineering Components' established recently in Manchester under the JIF initiative. This will be undertaken in collaboration with the UMIST Wolfson Unit for 'Optical Stress and Strain Measurement'.The project will involve the development of diacetylene copolymer coatings capable of undergoing controlled cross-polymerisation in UV light. Methods of application of these coatings to a variety of different substrates (eg metallic, polymeric, composite) will be investigated. The possibility of following the deformation of the substrate from strain-induced Raman band shifts in the coating will be investigated using a Renishaw 100 remote Raman spectrometer. This will involve modifications to both the hardware and software of the spectrometer in order to produce a practical instrument.The sensor system is potentially capable of measuring surface strain directionally to a precision of 0.01% in regions as small as 2 microns in size with no physical contact with the surface. It will have many potential applications for strain monitoring in the aerospace, transport, marine, construction and engineering industries.EngProg\
