Carbon Fibers 169<br />

The <strong>carbon</strong>-fiber industry is going through rapid changes <strong>and</strong>, at times,<br />

bewildering gyrations, both in the U.S. <strong>and</strong> abroad, as companies change<br />

ownership, licenses are granted, <strong>and</strong> partnerships created <strong>and</strong> dissolved.<br />

In addition, the internationalization <strong>of</strong> the business is spreading <strong>and</strong> it is<br />

becoming increasingly difficult to group the producers <strong>of</strong> <strong>carbon</strong> fibers by<br />

country since many operations are international in character <strong>and</strong> ownership.<br />

Table 8.2 is a partial list <strong>of</strong> <strong>carbon</strong>-fiber producers in operation in 1992,<br />

with their trademark <strong>and</strong> licences.<br />

1.3 Carbon <strong>and</strong> Graphite Nomenclature<br />

As seen in Chs. 3 <strong>and</strong> 4, <strong>carbon</strong> <strong>and</strong> <strong>graphite</strong> materials are polycrystalline<br />

aggregates, composed <strong>of</strong> small graphitic crystallites with varying<br />

degree <strong>of</strong> basal plane alignment.<br />

The structure <strong>of</strong> <strong>carbon</strong> fibers is mostly turbostratic with little graphitic<br />

character <strong>and</strong> may in some cases include sp 3 bonds (see below). For that
