Intermediate Modulus(equivalent to Toray 800) UD carbon fiber prepreg

We supply UD carbon fiber prepregs made from Toray 800 equivalent Carbon Fiber. These are mostly supplied in 50, 75, 100 gsm

All our prepregs are protected with wax paper on one side and plastic film on the other.

All our prepreg rolls are 1m / 1.27m wide; the Length is 50/100 meters.  10m rolls are available for sample orders

Advantages of using prepreg

  • Easy to process
  • Stable size, Easy to mould
  • Resistant to temperature and aging
  • Little unravel during transportation.

Scope of application

  • Manufacturing Fishing rods, tennis rackets, skateboards
  • Aerospace industry
  • Automobiles, yachts, Ships
  • Construction reinforcement

Methods of curing 

  • Autoclave
  • Out of Autoclave
  • Heat-press moulding
  • Heat-shrink wrapped

Ideal curing process for our prepregs

  • Once you take out the prepreg from freezer, let it defrost overnight.
  • For curing, first cure it at about 80C for about 30 minutes
  • Then raise to 120C, for 120 minutes.. If 130 C, only 60 minutes. About 4 hours if at 100 C
  • Wait untill the temperature lowers to 60 C , then remove mould

This is the process for our default/standard resin system, we also supply prepregs made using other epoxy resin systems with different Tg and curing temperatures.

Storage and Transportation

Our Prepregs can be stored at room temperature for about a month hence do not require freezer bags for transportation. But if stored in a freezer (at about -18°C) then our prepreg can last for more than 6 months.
