摘要：

The static field electrical conductivities of several discontinuous fiber composites are reported. Novel fabrication techniques are employed to produce systems of highly aligned and well-dispersed carbon fiber and coated carbon fibers. The thermal and breakdown properties of the matrix resin and breakdown behavior of the composites are examined. The distribution of orientations of the included phase is determined and recorded as an average orientation descriptor. Degree of fiber aggregation is found to be the principal determinant of bulk conductivity, eclipsing the effects of orientation and fiber fraction for the dilute concentrations investigated. A conductivity scale dependence is found for materials with tightly constrained microstructures.
