Overview

This subsection covers carbon fiber and other exotic fibers (aramid, UHMWPE, silicon carbide) made in the United States: what they are used for, what goes into them, the machines that make them, and the companies. It extends the textile theme: the same spinning-and-heat-treatment logic, sold into aerospace, defense, wind and energy.

Key Themes

  • Aerospace anchors U.S. carbon fiber. Hexcel’s 2024 sales were 63% commercial aerospace, with Airbus and Boeing about 55% combined.
  • Foreign owners built U.S. capacity. Zoltek (Toray) and Teijin are Japanese-owned; Teijin’s Greenwood plant paused production from mid-January 2026.
  • Precursor is the cost lever. PAN dominates; ORNL tests lignin, pitch and polyolefin.
  • Protective fibers are changing hands. Spectra is now Solstice; Kevlar moved to Arclin on 1 April 2026; Dyneema is Avient.
  • Ceramic fibers are a defense-adjacent niche. GE’s Huntsville SiC project and startup Free Form Fibers.
