"Are you oven curing this laminate right off the bat? If you have 'pre-heated' the oven (not good, you should plug it in when you insert the part), and leave it in too long (over 1 hour, or too hot), the laminate will stick as you describe. Try just allowing the laminate to cure at room temp overnight, then remove the mylar, then post cure the laminate."
I was confused by this reply since it seemingly contradicts the advice in Dave's videos and instructions. Perhaps I'd missed something. In any event I laid up another test part last night with only a single layer of Teflon release on the Mylar and... it worked perfectly!
While I'm elated to now fully understand the recipe I'm a bit bummed that I can no longer cure parts in an hour. :( I wanted to share his feedback in case others were frustrated as I was. On a side note that's a single wrap of Carbon/Kevlar hybrid fabric on a 38mm cardboard tube with the glassine layer peeled off and... it's insanely strong! I'll reiterate:
1 wrap over cardboard tube!! It would likely survive a
J570. Composites frickin' rock.
Having failed to release the film cleanly with all three methods to date I contacted Dave Triano and here's his reply:
