In this work, interfacial properties of carbon fiber/polymer composites were evaluated by electrical resistance measurements. During the wetting process of CF tows by epoxy resin, the change in electrical resistance ratio (CERR) was measured and analyzed. The testing results for different carbon fibers and epoxy resins exhibited different trends. The CERR was associated with the different Spreading conditions, and the interfacial properties were predicted by CERR measurements. The accuracy of predictions based on the CERR method during epoxy spreading wetting on CF tow was then assessed by IFSS and ILSS tests together.
