“…Structural health monitoring (SHM) has become an important process in maintaining the proper state of composite structures. One of the ways to execute it is by using approaches based on optical fibers, i.e., Raman or Brillouin scattering techniques [4][5][6][7], fiber Bragg gratings (FBGs) [8], interferometric [9] or polarimetric methods [10,11] (Figure 1). What makes optical fibers ideal for embedding in composites is the fact that silica glass optical fibers exactly match the properties of fiberglass-based composite materials.…”

‘Smart’ structural health monitoring of composite materials with optical fiber sensors is becoming more and more important, especially in the aviation industry. This paper presents an overview of hybrid fiber-optic sensing systems based on scattering techniques, fiber Bragg gratings, interferometric techniques, and polarimetric methods in structural health monitoring. The main purpose of this manuscript is to analyze the possibilities of using hybrid sensors based on fiber optics to monitor composite structures, with a particular emphasis on aircraft structures. Since it is difficult to indicate the most comprehensive approach due to different parameters of the described sensors, the review contains a detailed description of available solutions. We hope that this work will allow for a better and faster selection of the right solution for the problem at hand.

“…The optical fibre technology is often used for structural health monitoring of composite materials. Well known optical phenomena (optical radiation scattering, Bragg grating reflectivity, micro and macro-bend losses) can be used for mechanical behaviour monitoring [8,[25][26][27][28]. Additionally, luminescent optical fibres, embedded in the material structure, can be used for temperature monitoring [15].…”

The polymeric optical fibre technology can be successfully used for UV spectrum range radiation measurements.Anew type of fluorescent optical fibre optode is presented. The used fluorescent wave-shifter was used for UV-VIS conversion and radiation measurements. The linear characteristic with sensitivity 480 mW−1 is presented for UV range 7.2-13.6 mW. Presented optode construction advantages (small dimensions, low weight, high immunity to electromagnetic fields and distributed sensor architecture possibility) are attractive for numerous composite based engineering applications.

“…Composite materials are widely used in structures as they can reach high loads and strain measurements had been studied through different techniques: one of them is the strain gauges used to analyze the strain [12], the electron MoirÃ© method used to measure the strain distribution [13] and fiber optics sensors for strain measurements [14]. The development of non-destructive testing methods is the main challenge for the assessment of structural elements in existing constructions.…”

Composite materials are widely used in structural mechanics as they can withstand high loads; although after a while, they can present relative strain due to these loadings. In the present work, it is implemented digital image correlation using one laser-beam and the speckles created by its reflection to describe the mechanical behavior of fiber-reinforced composites submitted under compression test. Composites were tested in two set of arrays: the first was done with fibers orientated parallel to the load and the second was done with fibers randomly orientated, as it is known that the stress-strain evolution change according to the orientation of the fibers. Our method allows us to evaluate the heterogeneous strain evolution observed during the tests. Validity of optical strain-measurements is assessed against the results of an universal testing machine, a good correlation was found by comparing the results.
