As you can see the resin in not equally spread through surface. My product demands 2 layers of prepreg so when i stack the layers i turn the the sides with more resin facing each other then i combine them so the most resin is in the middle of fibres letting the vacuum do its job. When i vacuume the prepreg i use release film perforated and breather all stuck in vacuumbag. My tactic is 3h of vacuuming on room temp then 1-2h on 45C, 1h on 60C and 1h on 70C after that i cure it at 120C for another hour more This is my BEST result : So here is the problem why is here areas of pinhole free surface and with pinholes is it the resin not evenly spread the or the problem is my tactic of vacuuming any tips or help will be nice. P.S. I am using http://shop1.r-g.de/item/390102S vacuum pump Tags pinhole pinhole free prepreg Edited 9 Years Ago by primoz1111
