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

Hello Jamesw

I use a fast hardener with the epoxy and hold the part at 20-25 degrees and they can be removed from the mould in under 4 hours, not sure if this helps.

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.

If the part is purely cosmetic it may be worth trying a Urethayle Acrylate resin as it is possible to add 1-2% of cobalt to the resin before adding the catalyst ( DO NOT MIX COBALT WITH THE HARDENER, IT WILL EXPLODE ). Often these have a much lower viscosity than epoxies and subsequently infuse much easier. The cure times depending on the size of the part can be very quick indeed.

Thanks for the replies - I'm using the EC infusion resin - normally work with a 50/50 slow/fast hardener mix if that helps...

Ok this is an ambient cure resin and doesnt have the cure profile which I was hoping for. But there is no reason why you cant cure and post cure at the same time so you could warm your mould to and resin to 25C. Mix in your hardener ( not this may effect your working time ) once the part has infused slowly increase the temperature by a few degrees a minute until you reach 60 degrees. Once cured allow the laminate to cool slowly though before demoulding.
