technical field [0001] The invention relates to the technical field of detection, in particular to a detection system for the curing process of preparing anisotropic conductive composite materials. Background technique [0002] In the preparation process of conductive composite materials, there are usually impedance analyzer methods and optical fiber sensor detection methods for the detection of the curing reaction of composite materials, but both have limitations. The impedance analyzer method is expensive, and the high-precision impedance analyzer is very expensive; The optical fiber sensor detection method has a complex structure and many sensors are laid. Both methods cannot display the change of conductivity inside the conductive composite material in real time, lack detailed distribution information of conductive particles, and cannot prepare conductive composite materials with more accurate electrical properties by controlling the magnetic field and heating temperatur...
