Graphite has a hexagonal close‐packed crystal structure which is strong and stiff in the two directions of the basal plane and, in the third direction—perpendicular to the basal plane—is weak and compliant. High‐performance carbon fibers must make use of the strong directions while suffering from the poor properties of the third. This paper describes, from fundamentals, the processes used to produce high‐performance carbon fibers. The resulting fiber microstructures and the consequences of these structures on properties are presented.
