Teijin Carbon Europe unveils low-CO₂ HTS carbon fiber yarn

Teijin Carbon Europe, part of the Teijin Group’s carbon fiber business, presents Tenax Next HTS45 E23 24K in hall 6, booth G22 at JEC World 2025. The yarn is a 24K tow, meaning 24,000 filaments, and is based on the HTS high-tenacity fiber type, which the company links to processability and a track record in industrial and aerospace markets. Tensile strength exceeds 4800 MPa and modulus is 240 GPa. The potential CO₂ reduction is 35 % against regular filament yarn made with existing production processes.

The yarn is produced with renewable energy, with sustainable raw materials as an option. Teijin Carbon is also implementing new process technologies to reduce the environmental impact further.

The supply system rests on ISCC PLUS certification. Polyacrylonitrile, the precursor of carbon fiber, is made from several chemical building blocks, and both conventional and sustainable grades are available on the global market. The company plans to buy a growing share of precursor materials from recycling or directly from bio-based sources. At the show it presents its first fiber products that combine significant CO₂ reduction with progress toward circularity.

Marc Fette, CEO of CTC GmbH, an Airbus company, welcomes the yarn as a material that pairs performance with his company’s sustainability goals.

Why it matters

Teijin Carbon markets its fibers under the Tenax and Tenax Next brands and produces in Japan, the United States, Germany and Vietnam. The directory lists the Tenax HTS40 high-tenacity family, the Tenax IMS65 intermediate-modulus family and the Tenax TPUD thermoplastic tape, which is offered with HTS45 and IMS65 fiber grades.

The yarn adds a quantified carbon-reduction claim to Teijin’s HTS portfolio. Teijin’s work on rapid cure prepreg and resin for high-rate eVTOL and braided PAEK fabric covers the matrix and form side of the same structures business.
