Compression and Tangential Load Measurement by Cellular Textile Composite
This paper is concerned with a study of compression or tangential force measurement by smart cellular textile composite integrated with fiber Bragg Grating (FBG) sensor. Unit cells of a cylindrical composite shell have been fabricated from glass and polyester woven fabrics and epoxy and used to measure compression or tangential load. When the composite shell unit is under pressure or tangential load, axial strain induced in the FBG sensor can be determined by the Bragg wavelength shift obtained from an Optic Spectrum Analysis. The sensitivities of this device for compression load are 0.42nm/N (for the polyester composite) and 0.29nm/N (for the glass composite) and the measurement ranges are 0~2.1N (PET) and 0~1.3N (glass) , respectively. The sensitivities of this device for tangential load are 0.09nm/N (for PET tension), 0.05nm/N (for PET compression), 0.04nm/N (for glass tension) and 0.03nm/N (for glass compression), and the measurement ranges are 0~±3.43N (PET) and 0~±4.41N (glass), respectively. In these measurement ranges, the system can be used to monitor the compression and tangential load distribution for a large area.
