Add Directional Reinforcement with High Strength

Carbon Fiber Tow is the thread used to weave carbon fiber fabrics. As a standalone product, it can be used to make wound parts, pultrusion, or chopped as a local reinforcement.

This 24K tow (or yarn) is composed of 24,000 individual carbon filaments, which boast the highest ultimate tensile strength in the industry. The #2393 is ideal for adding directional reinforcement to fiberglass, KEVLAR®, and carbon components.


  • Comprised of 24,000 carbon fiber filaments
  • Available in 50, 100, and 250 yard rolls
  • Wets out easily with resin
  • It can also be used with a filament winder to create tubes, or used with our #1171-A Air Driven Chopper Gun to create chopped graphite fibers.
  • Fatigue resistance for durable strength


  • Use to build out fillets on carbon parts, for spar-wing reinforcement, and pultrusion.
  • To maximize the fiber properties, use with epoxy or vinyl ester resins.
  • Polyester resin is also suitable, and is primarily used in cosmetic applications where higher strength-to-weight ratios are not a factor.
