I'm trying to speed up my infusion work process - normally when the resin infusion is complete, I turn off the vacuum. Then leave overnight, then post cure.... I could transfer to the oven straight after turning off vac - any suggested ramps for this to achieve fast cure and 60-70 degree post cure?

Thanks,
James

I have often cured wet laminates in an oven, this is not that uncommon as it greatly spreads up cycle times when mass manufacturing components.

The trick is to conduct the infusion in the oven as well if possible to prevent damage to the bag and or catching an infusion pipe on the side of the oven as you load up. Somewhere on the datasheet it will tell you the optimum temperature you should go up to and for how long to cure it for. If you post up the resin name so I can search for the technical data sheet and possibly give you the answer if I can find it.

Personally I have always kept the vacuum pump running whilst the part is curing, once the part is under vacuum the pump is not working that hard to maintain the vacuum according to the Busch engineer I once asked.
