The use of optical fibre Bragg grating (FBG) strain sensors to monitor the condition of safety critical rail components is investigated. Fishplates, switchblades and stretcher bars on the Stagecoach Supertram tramway in Sheffield in the UK have been

Optical fibre Bragg grating sensors have been field-trialed for the monitoring of dynamic loading of fish-plates, stretcher bars and switchblades on a tram network, with the aim of developing a condition monitoring system. This paper provides prelimi

The commissioning of superconducting magnet coils was monitored using embedded optical fibre Bragg grating sensors (FBG) fabricated in highly linearly birefringent (HiBi) fibre. The HiBi FBG sensors monitored the internal strain developed in the coil

5th IET Conference on Railway Condition Monitoring and Non-Destructive Testing (RCM 2011).
The growth of tram and rail networks worldwide is being challenged by a demand for reducing the costs of operation and maintenance and this is driving a technology lead approach to solving the challenge. In this paper the use of an optical fibre base

Fresnel refractometry was used to follow the changes in the refractive index during the isothermal curing of a simple difunctional epoxy resin, a commercial formulated multifunctional epoxy blend, and the same two resin systems modified by the additi

A chirped long period grating (LPG) is used as a directional flow sensor by monitoring the change in the transmission spectrum upon immersion in an oil of refractive index higher than that of the fibre cladding. The change in profile of an attenuatio

A cascaded long period grating Mach-Zehnder interferometer is used to monitor the change in refractive index of a UVcured epoxy resin over a cure cycle. Fourier techniques are used to calculate the phase shift and frequency spectralamplitude of the a

Optimum performance from advanced composites requires careful control of the resin matrix during cure. This is to ensure there are no cure induced voids and to minimise the build up of internal stresses. Careful control of the process is also necessa

The use of fibre grating refractometers as a means of monitoring the cure of a UV-cured epoxy resin is presented. The wavelength shift of the attenuation bands of a long period grating and the spectral response of a tilted fibre Bragg grating sensor
