Evaluation of the measurement method for the electrical resistance change of unidirectional CFRP composites using electrical potential theory

摘要

For the measurement of the resistance change of electrically anisotropic unidirectional CFRP composites, DC 2 probe method is not appropriate for its strong dependence on the specimen surface condition. However, by using the adjusted Weibull scale parameter, such as 0.77 sigma_o for the present study, the surface effect on the DC 2 probe results can be evaluated quantitatively.
