The factors limiting the maximum strength of carbon coated fibers are considered. In spite of the variations in the inert strength, at room temperature the strength of fibers under investigation depends not on the drawing conditions, but on the properties of the carbon coating. The strength of weak carbon coated fibers with melted-in zirconia particles is also investigated. It grows with increasing carbon thickness (i.e. decreasing of fiber electrical resistance). When the carbon coating is thick enough (electrical resistance is less than 10 kOhm/cm), the fiber strength practically does not depend on the coating thickness and environment humidity and is more than two times higher than that of polymer coated fibers.
