S Glass Fiber Prepreg

S (or S-2) Glass fibres provide the highest level of performance available among glass fibres.

Produced with a higher level of silica than standard glass fiber products, S-glass fibres offer the ultimate physical properties, including high tensile and compressive strength, high-temperature resistance, and improved impact resistance.

Methods of Curing

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

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

The ideal curing process for our prepregs

Once you take out the prepreg from the 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 until the temperature lowers to 60 C, then remove the 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 keep it in a freezer at about -18°C, then it can last more than six months.
