Procesos

Each producer’s fiber differs from those of its competitors, and the processing details that give each brand its signature characteristics are considered to be intellectual property. The carbon fibermanufacturing process also is notoriously difficult and expensive. Tool-up of a single world-class production line is capital intensive — $25 million minimum for equipment alone — and can take up totwo years to implement. In fact, the cost can be much more.
In simplest terms, carbon fiber is produced by pyrolysis of an organic precursor fiber in an inert atmosphere at temperatures above982°C/1800°F.
Carbon fiber is also expensive due to its good mechanical properties and the fact that the material is very light.
 Carbon fiber manufacture, however, is a complex undertaking. These arepolymerization and spinning
Polymerization
The process begins with a polymeric feedstock known as a precursor which provides the fiber’s molecular backbone. Today the majority is derived frompolyacrylonitrile (PAN), made from acrylonitrile, which is derived from the commodity chemicals propylene and ammonia. 
Generally, precursor formulation begins with an acrylonitrile monomer, which is combinedin a reactor with plasticized acrylic comonomers and a catalyst, such as itaconic acid. Continuous stirring blends the ingredients, initiates the formation of free radicals within the acrylonitrile’smolecular structure. This change leads to polymerization, the chemical process that creates long-chain polymers that can be formed into acrylic fibers.
hahaha ahi ponla para que sea mas entretenidala clase, de que “viendo una caricature hace mucho tiempo fue cuando escuche el nombre de ese proceso por primera vez”

Spinning
PAN fibers are formed by a process called wet spinning. The dope isimmersed in a liquid coagulation bath and extruded through holes in a spinneret made from precious metals. The spinneret holes match the desired filament count of the PAN fiber. This wet-spun...
