For the purpose of increasing payload and reduce freight cost, lightweight composite tank containers used for Transportation have been progressively developed during the last years. Compared to conventionally produced cylindrical steel tanks, the fiber-reinforced solutions allow greater flexibility in the tank design. Despite a number of further material-related benefits of fiber-reinforced composites as non-conductive and non-magnetic behavior as well as corrosion resistance and high strength, the optimization of their thermal degradation properties during combustion is still a challenge. To improve the fire performance of lightweight composite containers, special intumescent fire protection coatings can be applied onto the outside tank surface. This paper presents fire tests on glass-fiber-reinforced plastic transport tanks with complex geometries sheltered with different surface-applied fire protection systems. To evaluate the fire resistance of the tank structures, a fiber optic monitoring system was developed. This system is based on distributed temperature measurements using high-Resolution optical backscatter reflectometry and pointwise reference measurements using fiber Bragg gratings. Thereby, all the fiber optic sensors were directly integrated in the composite layer structure of the tanks. The focus of the presented work is on the demonstration of capability of fiber optic monitoring system in such high-temperature application. Moreover, the fiber optic measurements provide new insights into the efficiency of intumescent coating applied for fire protection of fiber-reinforced plastic transport tanks.
We investigated the sensing properties of a single mode Poly Methyl Methacrylate (PMMA) Microstructured Polymer
Optical Fibre (MPOF) with mechanically imprinted Long Period Grating (LPG). We measured the influence of strain to
the LPG wavelength which showed the viscoelastic nature of PMMA. We also measured the influence of temperature
and humidity to the LPG wavelength.
We investigated sensing properties of single mode poly methyl methacrylate (PMMA) microstructured polymer optical
fibres (MPOF) with mechanically imprinted long period gratings (LPG). After preparation of the MPOF end-faces the
samples were elongated with silica fibres. These samples were used to measure the influence of strain to the LPG
wavelength which showed the viscoelastic nature of PMMA. We also measured the influence of temperature and
humidity. The results show that MPOF LPGs are well suited for strain sensing. One MPOF LPG was stitched to a
textile. Using this textile we measured a simulated respiratory motion.
This paper reports on a fibre optic sensor for heart rate measurement which is developed within the framework of the FP7 EU project i-Protect. Goal is integration of the sensor into personal protective equipment Two different sensor prototypes based on polymer optical fibre (POF) were developed. One is based on long period gratings in microstrutured POF and the other one is based on macrobending effects in POF.
