    Measurement of Mechanical and Thermal Strains by Optical FBG Sensors Embedded in CFRP Rod
    Research 2020 : January - March

    The present study intends to provide the photoelastic coefficient and thermal expansion coefficient needed to use an FBGembedded\nCFRP rod (smart rod) as strain sensor. Due to the monolithic combination of the FBG sensor with a CFRP rod, the\nsmart rod is likely to exhibit thermal and mechanical properties differing from those of the bare FBG sensor. A tensile test\nshowed that the photoelastic coefficient of the smart rod is 0.204, which is about 7.3% lower than the 0.22 value of the bare\noptical FBG....................
