A study on self-sensing properties of carbon fibre sheet as structural materials in civil engineering

摘要：

CFRP is used in civil infrastructures can play sensors as well as strengthening structural materials.The electromechanical properties of CFRP used in civil infrastructure are experimentally and analytically investigated in this paper.The CFRP strips are tested under monotonically uniaxial loading.The effect on the relationship of change rate of resistance and applied strain by the number of bundles in CFRP strips is also analyzed based on the test results.A modified parallel DC circuit model is suggested to simulate the relationship of change in rate of electrical resistance and applied strain of CFRP strips and the calculated results agree well with the test results.
