Anisotropic Electric Conductivities in Graphite Fiber Reinforced Composites
As a result of manufacturing processes, there is a strong tendency for the atomic basal planes in graphite to aligned preferentially along the fiber axis. Such fibers are anisotropic in their electrical properties. In composite laminates containing these fibers, the electrical properties are dependent on the precursors from which the fibers are made (e.g. pitch or PAN based), and upon the heat treatment the fibers and the composite have been subjected to after manufacturing.
