Phenolic oven cure
Phenolic oven cure
(OP)
I am working on an oven cure with phenolic resin and silica. I am running into trouble since phenolic resin is a condensation cure and am experiencing bubbles in the final cure. For the green state cure a vacuum bag is being used and then it has been taken off for the post cure. Does anyone have any suggestions on the green state cure to release the water and volatiles better? Also should the vacuum be maintained during the post cure? Mainly what is the best way to remove the volatiles to avoid bubbles and de-lamination?

If it is not structural then who cares?

I was wondering if you could share your cure temperature profile?

A key feature of the fab is on the top and bottom of the panels we place a layer each of dry glass, perforated FEP, and peel ply in order to draw out the volatiles. If we don't have these we will get porosity in the parts.
