Fibre optic sensors enable the measurement of strain and temperature in a comprehensive manner due to the distributed measuring technology based on the Rayleigh signal analysis. The measurement technique is suitable to determine the shear elasticity on small scale tests as well as to specify the load bearing behaviour of specimens at component scale. After determining and evaluating the elasticity of polyvinyl butyral in the laminated state at variable load velocities at room temperature, the present work shows its mechanical properties as a function of temperature. In terms of correlation between the measured signal and the real state of strain, it is necessary to define suitable adhesives for application fibre sensors on the glass surface in a wide temperature range and the behaviour of a single embedded fibre. Investigations on various adhesives using small-scale bending tests on monolithic glass are intended to determine both the rheology and the adhesion between glass and fibre sensor. The behaviour of embedded sensors in different adhesives is determined with an entirely new developed test set-up, which is used for the first time in this context. Small test specimens of glass are bent in time- and temperature-controlled experiments. The test generates a delineated region of homogeneous stress that is monitored by a couple temperature-compensated strain gauge circuit. The results provide a temperature- and time-dependent correlation between frequency shift of the measurement system and surface strain including effects such as slipping and relaxation of the used adhesives. The method for measuring the interlaminar shear modulus from the distributed strain of the glass surface is then presented as a consistent procedure using an analytical model of a uniaxially bent beam and its numerical solution.
