Thin Ply Prepreg

During these past 10 years, NTPT™ has developed techniques to spread fibers from untwisted tows. All types of fibers can be spread:

  • Carbon Fibers
    • Down to 30gsm for PAN-based fibers 
    • Even down to 15gsm for fibers such as
      MR70 12K
    • Down to 90gsm with pitch fiber K63712
    • Down to 40 gsm with pitch fibers such as YSH70
  • Glass Fiber down to 48gsm with S-glass 9 microns
  • Quartz Fiber down to 30gsm with 14 microns fiber
  • Aramid Fibers down to 20gsm
  • PBO and other synthetic fibers down to 30gsm or less

North Thin Ply Technology makes the thinnest unidirectional prepreg tapes in the world.

NTPT ThinPreg™ materials for UAVs

  • NTPT™ supplies prepreg systems for UAV components where absolute weight saving is critical for endurance.
  • Most carbon fibres (intermediate, high and ultra-high modulus fibres) including pitch fibres can be spread to the lowest aerial weights to deliver the ultimate in super light, super stiff structures.
  • These super low aerial weight products can be produced using a number of the NTPT™ ThinPreg™ resin systems.
