Teijin Limited’s Tenax carbon fibre and carbon fibre thermoplastic unidirectional pre-impregnated tape (Tenax TPUD) have been registered in Boeing’s qualified products list as an intermediate advanced composite material for primary structural parts.
Since Teijin and Boeing signed a Qualification Agreement in June 2016, the two companies have been working on material qualification testing and application study of carbon fibre-reinforced thermoplastics (CFRTP) for primary structure parts.

Tenax TPUD is a carbon fibre thermoplastic unidirectional pre-impregnated tape made with thermoplastic resin and achieves high heat, impact and fatigue resistances, and helps reduce production costs whilst improving component manufacturing efficiency due to its shortened moulding process.
Teijin focuses on the aircraft business as one of the growth strategies in its medium-term management plan for 2017-2019 and is intensively accelerating its development of mid- to downstream applications, such as cost-effective carbon fibres with higher-tenacity and higher-tensile modulus, intermediate materials including Tenax TPUD, carbon fibre thermoplastic consolidated laminate (TenaxTPCL), thermoset prepreg and non-crimp fabric.
Flying forward
Going forward, Teijin intends to further strengthen its carbon fibre and its intermediate material business as a leading solution provider for aircraft applications, targeting annual sales in this field in excess of $900m by around 2030.
Teijin brings advanced solutions in the areas of:
- environmental value;
- safety, security and disaster mitigation; and
- demographic change and increased health consciousness.
Its main fields of operation are high-performance fibres such as aramid, carbon fibres and composites, healthcare, films, resin and plastic processing, polyester fibres, products converting and IT.
The group has some 170 companies and around 19,000 employees worldwide.
Teijin plans to begin commercial shipments to Boeing approved parts makers within the next two years.
