Anyone have experience with making reusable vac bags for prepreg? I’m figuring that you’d still need a release ply and breather to get full compaction as the silicone could seal itself off around the laminate.
Maybe, on the other hand, you’d just need a breather from the vac port to the flashing/trimmed edge of the laminate? Possibly the uncured laminate could breathe itself until the resin fully wetted, at which point the vacuum would be established? Then you could maintain the ease of release property of silicone bags as well.
Food for thought, would appreciate any ideas or discussion.
