CompositesWorld’s annual Carbon Fiber conference was held in Knoxville, Tenn., U.S., in late 2019 and included a pre-conference seminar focused on carbon fiber supply and demand, presented by Tony Roberts, a longtime composites industry veteran and proprietor of AJR Consultancy.

Roberts spoke to a packed conference room of attendees eager for a snapshot of the state of carbon fiber manufacturing. This eagerness stems from the fact that carbon fiber manufacturers tend to hold carbon fiber capacity information very closely, thus it’s difficult to develop hard-and-fast figures. Roberts acknowledged as much in his presentation, and provided capacity estimates from other analysts to give his report context. That said, what follows is a summary of Roberts’ own data.

The accompanying tables summarize the supply and demand picture. On the supply side, there was 161,200 metric tonnes of global carbon fiber nameplate capacity in 2019. Toray (Tokyo, Japan) dominates the carbon fiber supply chain with 57,000 metric tonnes of annual capacity, which nearly equals the capacity of the next four largest suppliers combined. 

Carbon fiber supply, nameplate, metric tonnes

 Manufacturer Headquarters 2019
Toray  Japan 57,000
Hexcel  U.S. 16,000
Mitsubishi Chemical Carbon Fiber & Composites  U.S. 16,000
 Teijin  Japan 14,000
SGL Carbon  Germany 13,000
Formosa Plastics  Taiwan 9,000
Solvay Composite Materials U.S. 4,400
DowAksa U.S. 3,000
Hyosung South Korea 2,000
Various China 21,800
Various Rest of World 5,000
Total   161,200

In 2020, Roberts said to expect capacity expansion for Hyosung (Seoul, South Korea), which is adding 2,000 metric tonnes in Korea; Teijin (Tokyo, Japan), which is adding 2,200 metric tonnes in the U.S.; and Toray, which is adding 2,000-3,000 metric tonnes in the U.S. and Mexico. By the end of 2020, Roberts says, expect global nameplate carbon fiber capacity to be 172,000 metric tonnes.

Carbon fiber manufacturing in China is slowly maturing, with the largest suppliers there each with capacity of less than 10,000 metric tonnes. The five largest are Zhongfu Shenying Carbon Fiber (Lianyungang City, China), Hengshen (Danyang City, China), Jinggong Science & Technology (Shaoxing City, China), Weihai Guangwei Composite Materials (Weihai City, China) and Kangdexin Composite Material Group (Changping, China). Almost all, said Roberts, have expansion plans, but the most aggressive appears to be Kangdexin, which is said to be working toward an ultimate goal of almost 70,000 metric tonnes capacity.

The global demand for carbon fiber is complicated, mainly because it is offered in such variety — size (tow counts) and mechanical capability (strength, stiffness) — that making sense of the data requires a closer look at the end markets that use carbon fiber. That said, Roberts reported, 2019 saw total global carbon fiber demand of 123,300 metric tonnes, with the bulk of that, 85,000 metric tonnes, coming from the industrial segment, which includes wind energy, automotive, pressure vessels and infrastructure. Aerospace, which consumes the highest quality carbon fiber, accounted for 24,500 metric tonnes; the sports and leisure segment accounted for 13,800 metric tonnes.

Sports/Leisure 12,000 13,800  19,000
 Total 98,000 123,300  191,350


Looking ahead, Roberts is particularly bullish about increased carbon fiber demand from wind energy (27,300 metric tonnes in 2025), transportation (22,750 metric tonnes in 2025), infrastructure (20,800 metric tonnes in 2025) and pressure vessels (19,500 metric tonnes in 2015). Roberts expects the aerospace end market to demand 30,000 metric tonnes of carbon fiber by 2025, with 15,500 metric tonnes of that going to commercial aircraft. The balance goes to interiors, defense, business jets, general aviation, engines, rotorcraft, unmanned aircraft and munitions.

The upshot is that by 2025, it is estimated that the total carbon fiber demand will be 191,350 metric tonnes. Roberts expects global nameplate carbon fiber demand, by 2025, will be about 201,000 metric tonnes. Accounting for knockdown — the difference between nameplate and actual carbon fiber production — it is conceivable that the industry may see a carbon fiber shortfall in the next five years.

In any case, the carbon fiber supply chain is showing serious signs of maturation. The material, Roberts noted, is now available in almost every industrialized nation in the world.
