Teijin Unveils Advanced Carbon Fiber Woven Fabric
Tokyo, Japan, February 17, 2022 — teijin limitedtoday announced the launch of a lightweight, strong and economical woven carbon fiber fabric developed with the company’s proprietary tow-spread technology.
The new woven fabric is made with 3K (3000) carbon fiber filament yarn for applications requiring low weight and design flexibility, such as automotive interior materials and sporting goods. Teijin, using its internal yarn spreading technology, successfully thinned the 3K fabric from a casting thickness of 0.2mm to about 0.15mm, the same as that of the 1K woven fabric, when it is molded in carbon fiber reinforced plastic (CFRP).
Thanks to the flat crimps of the interwoven threads of the fabric, CFRP made with Teijin’s new fabric offers superior softness, resulting in more stable strength compared to CFRP made with 1K carbon fiber woven fabric (according to internal research by the company). In addition, the high efficiency of Teijin’s special tow-spreading technology lowers the cost of the fabric below that of conventional 1K carbon fiber woven fabric. Moreover, despite the use of 3K yarn (200g/m2), Teijin reduced weight by 35%, similar to fabric made with 1K yarn (125g/m2).
Teijin will now market its new fabric to manufacturers of industrial and sporting goods. Along with other spread-tow carbon fiber woven fabrics in the Teijin portfolio, the company is targeting sales of 2 billion yen in fiscal 2030. Going forward, Teijin will continue to strengthen its carbon fiber line with other innovative and high-performance materials and solutions. in a long-term vision of being a company that supports the society of tomorrow.
Strong, lightweight CFRP is widely used to improve performance and reduce weight in aerospace, industrial and sports applications. The stable strength needed to improve the mechanical properties of CFRP can be achieved by relaxing the stress concentration applied to the carbon fibers, resulting in a smoother woven carbon fiber fabric for use as a reinforcing material. As thinner and thinner carbon fiber filament yarns are used to produce thinner woven fabrics, the difficulty of producing such yarns can increase the costs of such fabrics.
