Carbon fiber is often time produced using two main methods: through the use of Polyacrylonitrile (PAN) and from pitch. Pitch is a viscoelastic material that is composed of aromatic hydrocarbons. Pitch is produced via the distillation of carbon-based materials, such as plants, crude oil, and coal. Pitch is isotropic, but can be made anisotropic through the use of heat treatments.
Carbon–carbon composites are fabricated using either the liquid impregnation method or CVI. In the former, the preform is impregnated with a polymer resin or coal tar or petroleum pitch which is then carbonized, i.e., heated in an oxygen-free atmosphere to cause volatilization of all elements (hydrogen, nitrogen, etc.) except carbon.

Pitch products are produced by Rain Carbon Inc. from coal tar pitch (CTP), a derivative of coal tar distillation, as well as from specialty petroleum feedstocks. CTP is mainly used as a binder for the production of carbon anodes essential for aluminum smelting.
Jan 14, 2020· Carbon fiber is made from organic polymers, which consist of long strings of molecules held together by carbon atoms. Most carbon fibers (about 90%) are made from the polyacrylonitrile (PAN) process. A small amount (about 10%) are manufactured from rayon or the petroleum pitch
Carbon Fiber Production Carbon fiber is currently produced in relatively limited quantities mostly via two manufacturing processes: A. Based on pitch (coal tar and petroleum products) B. Based on Polyacrylonitrile (PAN) Current global capacity for pitch-based carbon fiber is estimated at about 3,500 metric tons per year.
Jan 10, 2014· Carbon and graphite materials are manufactured according to processes based on conventional ceramic technologies.Raw materials such as petroleum cokes, pitch cokes, carbon black or graphite materials with a defined stone size distribution are mixed with a
Growth in the commercial aviation segment is projected to play an important role in fostering the industry growth. Raw Material Insights. The primary raw materials in carbon fiber manufacturing are polyacrylonitrile (PAN) or pitch. The superior properties of PAN are expected to result in wider acceptance in various applications.
Dec 19, 2008· The making of carbon fiber. Today about 10 percent of produced carbon fiber is made from a rayon- or pitch-based precursor, but the majority is derived from polyacrylonitrile (PAN), made from acrylonitrile, which is derived from the commodity chemicals propylene and ammonia. Trends in carbon fiber manufacturing.
Nov 24, 2016· ‘We’re taking the carbon and turning it into carbon fiber, so that’s effectively isolating it from going into the environment,’ he added. With the new Utah grant, Eddings and his team will analyze the makeup of Utah coal to determine how well it can be used for pitch-based carbon-fiber material.

Petroleum pitch is normally utilized for this function. For some high-density graphite grades, the carbon parts may go through the baking, pitch impregnation, rebaking cycle several times. Our GPX 1 graphite is manufactured using a raw graphite material that has been densified with pitch and rebaked.
Jul 05, 2018· However, carbon manufacturing is an energy-intensive industry. We must build digital process chains to optimize processes and minimize costs. The Manufacturing Process of Carbon Products. Typically, carbon products such as graphite are made from raw materials such as petroleum or coal tar pitch coke, pitch as a binder, and some additives.
