Teijin Co., Ltd. recently announced that its Tenax dry-reinforced carbon fiber material (DR) has passed the qualification certification of Airbus A320neo wing spoiler. This product uses resin developed by Spirit AeroSystems, one of the world's leading manufacturers of aircraft structural parts. Transfer molding (RTM) process. The highly automated RTM solution uses Tenax Dry Reinforced Non-crimped Fabric (DRNF) and Tenax Woven Fiber (DRBF) to form a protective layer and stiffeners while maintaining the existing product interface, so that all final spoilers can be directly replaced Components.
Tenax DRNF and Tenax DRBF are developed for resin infusion and resin transfer molding processes. Compared with traditional autoclave molding, it can provide higher productivity and component integration. Tenax DRNF is made by bundling carbon fiber filaments. According to the structural requirements of the final part, the carbon fiber filaments are dispersed into multiple layers in different directions in one direction.
The fabric has excellent fiber orientation, its mechanical properties are better than conventional woven fabrics, and its performance is equivalent to aerospace-grade thermosetting unidirectional prepregs. Tenax DRBF is used as a cavity filler in the structure of the spoiler component. These materials have been individually certified by Airbus for this application.
The combination of Tenax DRNF and Tenax DRBF achieves Spirit AeroSystems aircraft component production standards such as effective processing capacity, productivity and cost efficiency. The A320neo spoiler components will be produced at Spirit AeroSystems' new mass production plant in Prestwick, Scotland.
As one of the strategic priorities of its mid-term management plan for 2020-2022. Teijin is accelerating the development of mid- and downstream applications for aircraft, such as cost-effective carbon fiber with higher strength and higher tensile modulus, intermediate materials including Tenax dry reinforced carbon fiber materials, and carbon fiber thermoplastic unidirectional prepreg tape (Tenax TPUD), Carbon fiber thermoplastic reinforced laminate (Tenax TPCL) and thermosetting prepreg. Looking to the future, Teijin plans to further strengthen its carbon fiber and intermediate materials business, and strive to become a leading solution provider in the aircraft application field. It is estimated that by 2030, the annual sales in this field will exceed 900 million US dollars.
