I really like that ACP Composites website- very nice lay out! So here's what I'm thinking- since I'm not doing a traditional wet lay-up, I could layer up the stock like this:non-porous release film, breather cloth, outer bag... This way, the epoxy would still get pulled through the fiberglass, but I should be able to re-use the breather cloth and outer bag for a few stocks... Again- all I need is to set the fiberglass into place, with no bubbles. That's the goal.
Non porous release won't let the ply debulk (aka remove trapped air) the ply(s). 34 years working with aerospace composite layups. What release were you planing to use? I've used FEP for most of the years. You could perforate a non perf release to allow an air path. You also could just use a piece of blanket for a breather. I used to use N10 as a breather but we were also curing the part or laminate in an autoclave at temps between 250f and 400f using up to 125 psi. You are using room temp cure resin and just vac for your parts so you don't need anything fancy. It's too bad you live on the other side of the country.
