Teijin Limited announced that its Tenax carbon fiber and carbon fiber thermoplastic unidirectional pre-impregnated tape (Tenax TPUD) were qualified by Boeing and registered in its qualified products list. Teijin will supply Tenax TPUD as an intermediate advanced composite material for primary structural parts for Boeing.

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 fiber reinforced thermoplastics (CFRTP) for primary structure parts. Tenax TPUD is a carbon fiber thermoplastic unidirectional pre-impregnated tape made with thermoplastic resin and achieves high heat, impact and fatigue resistances and helps to reduce production costs and improve component manufacturing efficiency thanks to its shortened molding process. Teijin plans to begin commercial shipments of Tenax TPUD to Boeing approved parts makers within the next two years.
