Abstract
An anomalous temperature dependence of electric resistivity in carbon fibri ls in the range from 11 to 350 K is considered. The fibrils are prepared fr om the polyacrylonitrile fibrils by heat-treatment. A heterogeneous model o f conductivity is developed and a fit to the experimental dependencies of r esistivity is obtained. The adequacy of this model to a fibril conductivity problem is explained.
