Confirming electrical conductivity in carbon fiber reinforced plastics (CFRP) usually necessitates the utilization of multiple testing approaches. One common method is the Four-Point Probe Test, alongside the two-point Probe Method. In these tests, the material's resistivity is gauged by transmitting a known electric current through the sample using two external probes, while simultaneously assessing the voltage drop across two internal probes. These measurements facilitate the calculation of resistivity, hence determining conductivity.
