Teijin Carbon Europe, based in Wuppertal, Germany, has completed a Nadcap audit and been awarded accreditation covering the manufacturing and testing of non-metallic materials.

Nadcap, the National Aerospace and Defense Contractors Accreditation Program, is run by the Performance Review Institute (PRI). It audits special processes used in aerospace and defense supply chains and sets demanding requirements for process control, quality assurance and documentation.

Jana Kubitz, Head of Aerospace Marketing, EMEA, calls the result a milestone that reflects the company’s focus on technical excellence and quality. She adds that, for customers, the accreditation points to reliability and precision, particularly in safety-critical applications.

Teijin Carbon expects the accreditation to improve its competitiveness and to open access to new markets and customer segments, with aerospace named as the main area.

Why it matters

Teijin Carbon is a subsidiary of the Japanese Teijin Group and develops carbon fibers and fiber-based materials under the Tenax and Tenax Next brands.

For airframe and component manufacturers qualifying materials for certified platforms, an audited accreditation of material manufacturing and testing gives a documented process record at the supplier level. This applies to eVTOL and Group 2–3 UAS programmes, where structure suppliers must trace materials through certification.

Teijin’s range relevant to these programmes includes Tenax TPUD, a thermoplastic unidirectional prepreg. It is available with PEEK, low-melt PAEK and PPS matrices, and in HTS, UTS and IMS fiber grades. Two further fiber families, Tenax HTS40 and Tenax IMS65, are listed in the directory.

The company has been expanding its aerospace offering toward higher production rates. It has introduced a rapid-cure prepreg and resin system for high-rate eVTOL, and with A&P Technology a braided PAEK fabric for high-rate composites. It also unveils a low-CO₂ HTS carbon fiber yarn.
