Nanocyl EPOCYL™ NC R2HM-01 Formulated Epoxy-Carbon Nanotube Pre-preg Resin System
Categories: Polymer; Thermoset; Epoxy; Epoxy/Carbon Fiber Composite

Material Notes: EPOCYL™ NC R2HM-01 is a formulated epoxy based resin system for hot melt pre-preg and pressure molding processes, modified with our own Carbon Nanotubes (CNT), specifically developed to enhance the mechanical properties of the final fiber reinforced composite materials.

Applications: High performance composite parts

  • Automotive (bumpers and other structural parts)
  • Marine, especially sailing boats (structural outer shell in carbon fiber composite, masts and other generic structural parts)
  • Industrial parts (rollers, doctor-blades and wind-mill blades)
  • Sporting equipments (bike frames, hockey sticks, tennis rackets, skis and golf shafts)
  • Aerospace (structural parts and interiors)

Advantages

  • Improved fracture toughness (G1C) of over 100%
  • Improved strength perpendicular to, and at +/- 45° to fiber direction of over 15%
  • Reduced CTE of over 15%
  • Easy and ready to use system for hot melt pre-preg processes
  • Higher uniformity of temperature during curing (avoids hot-spots)

Curing agents EPOCYL™ NC R2HM-01 can be cured or cross-linked with different types of curing agents depending on the properties desired in the final composite.

The type of curing agent suggested is Aradur 5021 (Huntsman). Anyhow, any curing agents based on dicyandiamide are the preferred ones to be used in combination with EPOCYL™ NC R2HM-01. It is important to respect the ratio hardener/accelerator with the epoxy equivalent of the EPOCYL™ NC R2HM-01.
