Carbon Fiber Prepregs

Carbon fiber prepregs are manufactured by the infusion of carbon fiber cloths with a controlled amount of  epoxy resin.

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; Length is 50/100 meters.  

We have Carbon fiber prepregs in Uniderectional, Plain and Twill  weaves.

Advantages of using prepreg

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

 

Scope of application 

  • Fishing rods, tennis rackets, skate boards
  • Aerospace industry
  • Automobiles, yachts, Ships
  • Concrete reinforcement

 

 

Methods of Curing

Our Prepregs are extremely convenient to work with and can be processed in a variety of methods:

  • 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

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 you store it in a freezer at about -18°C then it can last more than 6 months.
