Carbon Fibre/Silicon Composite Sensors for Concrete Structural Health Monitoring in Compression


Article Preview

Structural health monitoring of concrete infrastructures has attracted enormous attention due to the brittle nature of concrete. In this research, we report the carbon fibre/silicon rubber composite sensors and their excellent monitoring in concrete’s compression. It is shown that the electric resistance change synchronously with the mechanical deformation of concrete during the compression process. With the increase of carbon fibre fraction, the sensitivity decreases and the numerical equations to predict the structural change are also obtained. The experimental results reported here highlight the potential application of CF/silicon composites as an effective, real-time structural monitoring sensor with low-cost and long life.
