Abstract
It focuses on a composite material made of glass and carbon fibers in this paper. The composite can be actively monitored and controlled by the self-sensing of the carbon fibers. However, due to the high stiffness and brittleness of the composite material, damage often occurs instantaneously. It is difficult to monitor damage patterns and control damage through factors such as fiber type variables and displacement relationships. This is why monitoring the health of composite fibers is an important direction, which has major implications for the aerospace, industrial and automotive sectors. In this project, the main focus is to monitor the electrical conductivity of carbon fibers online by breaking thin layers and observing the changes in their conductivity, and to understand changes in condition through changes in current. In addition, the composite design of this project can be applied to the monitoring of large planar materials, as well as to applications in important areas such as aerospace. In making further comparisons, it can be seen that the 5 mm thin layer of carbon fiber is more sensitive in the process of self-sensing, while the change in resistance is more noticeable when damage is received in the period.
