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.
