Methods of Curing
Our Prepregs are extremely convenient to work with and can be cured or laminated in a variety of methods:
Out of Autoclave
Heat-press moulding ( this is how we make our laminated carbon fiber sheets)
For our prepregs , ideal curing process is :
1. Once you take out the prepreg from freezer, let it defrost overnight.
2. For curing, first cure it at about 80C for about 30 minutes
3. Then raise to 120C, for 120 minutes.. If 130 C, only 60 minutes. About 4 hours if at 100 C
4. Remove the mould at about 60 C.
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 -20°C then it can last more than 6 months
