From page 119...
... Coagulation bath A liquid bath that serves to harden viscous polymer strands into solid fibers after extrusion through a spinnerette. Used in wet spinning processes such as rayon or acrylic fiber manufacture.

... Crystalline orientation implies the extent to which these crystalline regions can be aligned parallel to the fiber axis. Crystalline orientation is an important factor in determining the mechanical properties of carbon fibers.

From page 121...
... Induction furnace In the carbon fiber process, a carbonization furnace that utilizes induction heating to eliminate the heteroatoms from the carbon fiber structure. Heat distribution is obtained by a combination of induced heat to a furnace muffle/susceptor within the induction coil and radiation from the interior surfaces of the furnace chamber in temperatures in excess of 3000°C.

... Also, the study of the fine structure of a fiber or other material, such as basal plane orientation across a carbon/graphite fiber. A high molecular weight material left as a residue from the destructive distillation of coal and petroleum products.

From page 123...
... A high-temperature resistant thermoplastic polymer with the sulfone linkage, with a Tg of 190°C. A vinyl-type thermoplastic resin formed by the addition reaction of vinyl chloride monomer.

From page 124...
... Rayon fibers were one of the first precursor materials to be used in the manufacture of carbon fibers. They have now been almost completely replaced by PAN and pitch fibers as starting materials for carbon fiber manufacture due to low yields, high processing costs, and limited physical property formation.
