The thesis
Core thesis
Carbon fiber is 5x stronger and 2x lighter than steel. Boeing 787 is 50% composite by weight. Wind turbine blades require carbon fiber for length/strength ratio. Toray (Japan) dominates production. The barrier: cost ($15-30/kg for aerospace grade) limits mass automotive adoption. BMW's carbon fiber strategy retreated from mass-market to high-performance only.
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.
