Towpreg Solutions by Teijin Carbon
High‑performance epoxy-based tow prepregs for advanced manufacturing
Teijin Carbon offers a comprehensive portfolio of epoxy-based tow prepregs engineered for a wide range of manufacturing requirements - from filament winding to highly automated processing environments.
Based on Tenax™ carbon fiber and specially formulated thermoset resin systems, our towpregs deliver outstanding composite performance, increased throughput, and long-term cost efficiency. These materials are trusted across industrial applications, defense technologies, and emerging new-space markets.
Our product range is structured into two main groups:
- Conventional towpregs
- High‑performance towpregs
Conventional Towpreg
Optimized for high-speed filament winding, our conventional towpregs combine Tenax™ carbon fiber (800 – 1600 tex) with an epoxy resin system designed for robust handling and reliable processing at room temperature.
These materials deliver the stability and performance needed for efficient, continuous production.
Benefits
- Controlled resin content
- Highly efficient material for winding applications
- Improved shelf life: > 6 weeks at room temperature
- Glass transition temperature (Tg): ~120 °C
- Outstanding workability and consistency
Our high-performance towpreg is precisely width‑calibrated to 6.35 mm (1/4") and available in various fiber types and backing film configurations. Tailored for automated fiber placement (AFP) systems and other advanced manufacturing environments, this product ensures exceptional dimensional stability and repeatable performance.
Material Solution
The system is based on Tenax™ carbon fiber (800 – 1600 tex) and a performance‑engineered epoxy resin, providing durability, optimized tack, and high mechanical performance.
Benefits
- Controlled width and resin content
- Cost‑optimized solution for high‑end applications
- Improved shelf life: > 6 weeks at room temperature
- Glass transition temperature (Tg): ~150 °C
- Tailor‑made variants available to meet specialized customer needs
