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.
