OvenCure Cycle-
Apply 26-28”Hg vacuum - Increase from room temperature to 265 °F (129 °C) at a rate of 0.9-3.6 °F/min (0.5-2.0 °C/min)- Hold cure temperature for 4 hrs +/- 0.2 hrs- Cool down to 150 °F prior to removalOptional Free Standing Post Cure- Increase from 265 °F to 365 °F (129 °C to 185 °C) at a rate of 0.9-3.6 °F/min (0.5-2.0 °C/min)- Hold cure temperature for 120 to 130 minutes- Cool down to 150 °F prior to removal.E-752-MTS Out-of-Autoclave and Autoclave Example Cure Cycles
Autoclave Cure Cycle-
Apply 28”Hg vacuum and 15 psi pressure (1 bar)- Increase from room temperature to 230 °F (110 °C) at a rate of 0.9-3.6 °F/min (0.5-2.0 °C/min)- Vent Vacuum when temperature reaches 212 °F (100°C)- Increase pressure from 15 psi to 45 psi (1 bar to 3.1 bar)- Increase from 230 °F to 350 °F (110 °C to 177 °C) at a rate of 0.9-3.6 °F/min (0.5-2.0 °C/min)- Hold cure temperature for 120 to 150 minutes- Cool down to 150 °F and relieve pressure prior to removal
