Enabling high rate aerospace: How Teijin Carbon’s rapid cure materials accelerate the next generation of flight

15. September 2026 | Blog

With rapid cure prepregs and fast‑curing resin systems, Teijin Carbon provides key material solutions for the high‑rate aerospace programs of tomorrow.

EVTOLs, hybrid regional aircraft, electric propulsion, and new Urban Air Mobility concepts are transforming the aviation landscape. At the same time, production volumes are expected to rise dramatically across all segments. Several emerging manufacturers are planning to scale from dozens to hundreds – or even thousands – of aircraft per year.
 

The commercial aviation sector is also returning to higher production volumes — from narrow body aircraft to regional platforms — reinforcing the industry wide need for faster and more repeatable composite manufacturing processes.
 

Such growth demands a new generation of composite materials that are faster to process, more energy efficient, highly automated, and consistently aerospace grade.

Teijin Carbon is well prepared for this shift. With deep experience in rapid cure technologies, we support high rate aerospace manufacturing through two complementary material approaches:

  • - Tenax™ rapid cure prepreg systems (Q-183)
  • - Rapid cure resin systems combined with dry fiber technologies (TR022 + DFP/NCF)


Prepreg remains essential in the new aerospace era

Prepreg based on Tenax™ carbon fiber continues to play a vital role in electric and hybrid aviation. Multiple eVTOL, propulsion, and regional aircraft programs rely on Tenax™ prepregs for reliable, high performance components.
 

Rapid cure prepregs are increasingly used in rotors and other composite structures within eVTOL, where predictable processing and certified performance are essential. They combine lightweight construction, stable quality and proven airworthiness — all in one material system.


Teijin Carbon’s rapid cure prepreg  – faster cures for high-rate aerospace


Tenax™  Q-183 is a fast curing thermoset epoxy prepreg engineered specifically for rate driven aerospace structures.


Key advantages

  • - 20 minute cure at 160°C, no post cure
  • - Ideal for secondary structures, fairings, covers, panels, movables
  • - Excellent hot/wet performance
  • - Compatible with press, autoclave, and VBO processes
  • - Well suited for eVTOL and hybrid aircraft, where production rates are expected to increase significantly
  • - Supports the efficiency and weight targets of electric flight


Q-183 enables manufacturers to scale production without sacrificing structural performance – a critical factor as aerospace moves toward higher output.


Rapid cure resin TR022 + dry fiber technologies – high-rate aerospace via RTM, HP-RTM & Infusion

Liquid molding technologies such as RTM, HP RTM, and infusion – in which dry fiber preforms are impregnated with resin inside a closed mold – are becoming essential for producing high rate aerospace structures. TR022, Teijin Carbon’s rapid cure epoxy resin system, is engineered specifically for these processes and enables fast, energy efficient manufacturing across all liquid molding routes.


These technologies offer key advantages for next generation aerospace production:

  • - High automation
  • - Lower process energy
  • - Attractive cost structures
  • - Strong scalability
  • - Design freedom for complex geometries


When combined with Teijin dry fiber materials, TR022 delivers high mechanical performance and a glass transition temperature of 212°C – suitable for demanding primary and secondary aerospace structures. Teijin provides a comprehensive dry fiber portfolio – from NCF fabrics to UD tapes – engineered for drapeability, mechanical performance and rapid cure compatibility.


Teijin’s resin systems and reinforcement materials are engineered to work as an integrated system – supporting predictable processing and high rate manufacturing.


For eVTOL, hybrid and commercial aircraft OEMs planning aggressive ramp ups, combining rapid cure resin systems with DFP and NCF technologies offers a scalable path toward fast, consistent and cost efficient composite manufacturing.


Rising production rates: Why rapid cure matters now

Next generation wings, electric propulsion housings, fuselage structures – all require materials that enable:

  • - Shorter cycle times
  • - Lower curing energy
  • - Automated and repeatable processes
  • - Stable aerospace grade quality
  • - Viability for serial production, not just prototypes


Rapid cure technologies are designed exactly for this environment.
