Experimental study and analysis of a polymer fibre bragg grating embedded in a composite material

Journal Article


Abstract


  • The characteristics of polymer fiber Bragg gratings

    (FBGs) embedded in composite materials are studied in this

    paper and are compared with characteristics of their silica

    counterparts. A polymer FBG of 10 mm length which exhibits a

    peak reflected wavelength circa 1530 nm is fabricated and

    characterized for this purpose. A silica FBG with a peak reflected

    wavelength circa 1553 nm is also embedded in the composite

    material for a comparison study. The fabricated composite

    material sample with embedded sensors is subjected to

    temperature and strain changes and the corresponding effects on

    the embedded polymer and silica FBGs are studied. The

    measured temperature sensitivity of the embedded polymer FBG

    was close to that of the same polymer FBG in free space, while

    the silica FBG shows elevated temperature sensitivity after

    embedding. With an increase in temperature, spectral

    broadening was observed for the embedded polymer FBG due to

    the stress induced by the thermal expansion of the composite

    material. From the observed wavelength shift and spectral

    bandwidth change of the polymer FBG, temperature and thermal

    expansion effects in the composite material can be measured

    simultaneously.
