Abstract: Composite materials are recently used in civil applications, in strengthening of masonry and concrete structures. They offer many advantages, in comparison with traditional techniques, mainly related to the favourable strength to weight ratio. Besides, monitoring the structure during its lifetime is very important, in order to detect possible anomalous situations. The innovative and original multifunctional textile, described in this work, is conceived to perform both these functions: thanks to a tube woven inside the fabric during manufacturing process, a fibre optical sensor can be inserted successively inside this tube, directly on the reinforced structure, allowing the structural health monitoring. Tensile tests on composite material performed with the textile allowed the mechanical characterization and the identification of the gage factor of the embedded sensor. Moreover, flexural tests, carried out on small scale samples reinforced with the textile, allowed to test the measuring performance of the textile in possible real applications.
