Fiber-optic sensors based on highly birefringent (HB) polarization-maintaining (PM) fibers represent a promising
generation of sensing devices also known as polarimetric fiber sensors. They utilize polarization (phase) modulation
within fibers to sense external perturbations . HB polarimetric sensors can be made temperature insensitive but to
measure strain they require means for setting a zero strain reference. Composite structures are made from two or more
constituent materials with significantly different physical or chemical properties and they remain separate and distinct in
a macroscopic level within the finished structure. This feature allows for the introduction of an optical fiber sensors
matrix into the composite material. In this paper we present experimental evidence that the interactions between the
composite material and optical fibers during manufacturing process are very significant. The lamination process can
dramatically change the strain sensitivity of the highly birefringent (HB) fibers.
The aim of the study was to develop an innovative processing method of magnetorheological elastomers (MRE). This method comprises optimization of the MRE structure in the context of their performance in the magnetic field. The influence of the amount of ferromagnetic particles and their arrangement in relation to the external magnetic field was investigated. As matrixes various elastomers, with different stiffness, were used. Their properties were compared with commercially available silicone rubbers. It was found that the structure of the MRE produced depends on the viscosity of the matrix before curing and the magnetic field strength applied. Two different magnetic field strengths were used: 100 and 300 mT. The amount of the carbonyl iron particles was equal to 1.5, 11.5 and 33.0 vol. %. Scanning electron and light microscopy techniques were used for the MRE microstructure observations. The influence of curing conditions on the thermal properties of the MRE was investigated. To evaluate the external magnetic field effect on the magnetorheological properties a deflection under magnetic field was measured. The experiment showed that application of the magnetic field increases stiffness of the material.
