Carbon fiber composites
Carbon-fibre supply needs to be broken down by grade, qualification and where it is made. Toray's March 2026 capacity table covers Japan, France, the US, South Korea, Hungary and Mexico. A Japanese owner does not mean production in Japan. Installed capacity does not tell us utilisation or which end market drives demand.

State of the art (2026)
Carbon fibre in 2026 is a mature, concentrated advanced-materials business. Aerospace remains the anchor: CFRP holds more than half the aerospace composites market, and wide-body demand on the Boeing 787, 777X and Airbus A350 has recovered to roughly 2019 levels, sustained by long-term Toray and Hexcel prepreg supply deals. Five producers – Toray (with Zoltek), Teijin, Mitsubishi Chemical, SGL and Hexcel – control about three-quarters of fibre supply, with Japan dominant. Aerospace-grade fibre still runs near $15–30/kg, capping mass-automotive use; BMW long ago retreated to high-performance only. Hydrogen pressure-vessel capacity (Toray's South Carolina line, online from 2025) is the clearest growth vector, while recycled carbon fibre remains a small, sub-$300M niche.
Core thesis
Carbon-fibre composites are used where low weight justifies a higher price. The Boeing 787 is 50% composite by weight. How strong and light a carbon-fibre part is depends on the grade of fibre, the resin, how the layers are laid up and the direction of the load, so a comparison with steel only holds for a specified part. For cars and trucks, the US Department of Energy treats composites as one of several ways to make components lighter. Toray of Japan is a leading producer, with plants in Japan, France, the US, South Korea, Hungary and Mexico.
