Carbon fiber tubes

High quality products thanks to pultrusion and pullwinding technologies.

Thanks to our industrial manufacturing processes (including Pultrusion, Pullwinding or K1 technologies) and extensive experience in composite materials, Epsilon designs and manufactures composite tubes in all shapes (round, square, rectangle, oval or special shapes) using materials tailored to your needs: :

  • Epoxy matrix (or other specific matrices as required),
  • Carbon fiber adapted to mechanical stresses : High Resistance (HR), Intermediate Modulus (IM), High Modulus (HM) or Very High Modulus (THM),
  • Natural fibers (flax, hemp, basalt,…),
  • Synthetic fibers,
  • Function integration (fiberglass or thermoplasic insulating/protective layer),
  • Finishing (machining, assembly, non-destructive testing…).
