Fibermax general purpose prepregs are based on a 80 to 150 oC (176 – 302 oF) curing toughened epoxy matrix, suited for both autoclave and press molding applications. A standard autoclave curing cycle is: Draw vacuum (0.6 – 0.7 bar) and apply positive pressure. Then start heating – typically 2-5 oC / min (3.5 – 9 oF) – till 120 oC (248 oF) and then hold this temperature for 1 hour. Turn off the temperature and cool under pressure to 60 oC (140 oF). When fully cooled open the bag and extract the piece.
4 – 6 weeks at room temperature
Allow prepreg roll to reach room temperature before opening plastic bag to prevent condensation.
