T1 - Monitoring of the rotor blades of wind turbines by fibre optic sensors N2 - In order to monitor the mechanical behaviour of the rotor blades of wind turbines, fibre optic sensors are increasingly attached to or embedded in the blades. Usually, fibre Bragg grating sensors arrays are then used. In order to investigate how stable and reliably work such sensors, fibre Bragg grating arrays were embedded into textile-reinforced composite. Long-term temperature and tensile (fatigue) tests have been carried out with composite structure specimens. This paper reports on selected results of the tests and discusses important reliability aspects with regard to the fibre design and the fibre material.

T1 - Fiber Bragg grating sensors for monitoring of wind turbine blades N2 - Fiber Bragg grating sensor arrays can be used to monitor the mechanical behavior of rotor blades of wind turbines. In order to investigate how stable and reliably work such sensors, different fiber Bragg gratings were embedded into textile-reinforced composite. Long-term temperature and tensile (fatigue) tests have been carried out with composite structure specimens. This paper reports on selected results of the tests and discusses important reliability aspects with regard to the fiber design and the fiber material.

A1 - Weinand, U. T1 - Fibre Bragg gratings as high dose radiation sensors? N2 - We have measured for the first time the shift of the Bragg wavelength and other parameters of fibre Bragg gratings (FBGs) exposed to radiation at different wavelengths up to a dose of 100 kGy. The results show that the FBG sensitivity to radiation increases from 820 nm to 1516 nm so that FBGs with higher Bragg wavelength, e.g. 1.55 µm, are good candidates for high dose radiation sensing: no saturation was observed up to 100 kGy and the measured wavelength shift was fairly independent on the radiation dose rate.
