Teijin Carbon Advances High-Performance Cycling with Aerospace-Grade Prepreg Systems

High-end bicycle manufacturers are entering a new era where frames and components must be lighter, stiffer, tougher, and more sustainable, all while enabling fast, repeatable, and cost-efficient production. To meet these demands, Teijin Carbon is expanding its portfolio of advanced prepreg systems, specifically tailored for premium road, gravel, and mountain bike applications.



Drawing from its aerospace heritage, Teijin Carbon utilizes resin systems, fiber grades, and layup technologies originally engineered for certified aircraft structures. This expertise has resulted in a sports-focused prepreg range designed to help bicycle brands achieve new levels of performance, structural reliability, and design freedom.


"Lightweight alone is no longer enough in high-end cycling. Brands now look for a balanced combination of stiffness, toughness, durability, flexural performance, and sustainability," said Yuki Tamenaga, vice president Global Sports Marketing & Strategy at Teijin Carbon. "By transferring our aerospace-proven composite expertise into sports applications, we are building prepreg systems designed for the next generation of bicycle innovation.


Teijin Carbon's sports portfolio includes several advanced material systems tailored to meet the complex performance requirements of frames, forks, rims, and other structural bike components. High-toughness resin prepregs are designed for impact-critical use cases such as cross-country, trail, and enduro riding, delivering enhanced crash durability and fatigue resistance while preserving stiffness and load path stability. High-flexural strength resin systems are optimized for stiffness-to-weight balance in road and gravel applications, supporting efficient power transfer, precise cornering response, and high stability under dynamic loads.


Hybrid prepregs, which combine the benefits of thermoset and thermoplastic matrices, enable improved interlaminar strength, reduced delamination risk, and tailored local reinforcements. These features are ideal for next-generation geometries and complex load paths. Aerospace-grade carbon fibers, originally engineered for aerospace structural applications, offer high strength, intermediate modulus performance, and outstanding compression behavior. These fibers are now available for high-end bicycle designs requiring maximum lightweight efficiency.


As bicycle OEMs accelerate their sustainability initiatives, Teijin Carbon is supporting the transition with innovative solutions, including Tenax Next low-carbon fibers, ISCC PLUS certified feedstock and supply chain transparency, and bio-based resin development programs. These technologies enable bicycle brands to reduce lifecycle environmental impact while maintaining or exceeding expected performance levels.

Today's KNOWLEDGE Share : What Is Going Wrong in UK Plastics Recycling?

Image
Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share : Robotic 3D printing can compete with traditional boatbuilding

Image
Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
