Strain Measurement in Two-Dimension Stresses Based on Polymer-Matrix Carbon Fiber Smart Stripes

Abstract:

The paper aims to sense strains of structures in two-dimension stress states and to perform a large-region strain monitoring. Polymer-matrix Carbon Fiber Smart Stripes (CFSS) distributed in two ways are stuck on a bending plate to detect strains using the piezoresistivity of CFSS. Monotonous tests are conducted to calibrate the surface piezoresistivity of the CFSS and then cyclic tests are conducted to measure the strains of the structure using the constitutive relation of CFSS. Results show the experimental values by CFSS fairly good with those by gage factors.
