Hello all,
1st Question:
Can anyone tell how I can eliminate the voids I get around the edges/corners of my foamcore during a vacuum bag lay up? My layup is a lamination of fiberglass, wood, foam core & carbon fiber. I believe my all my layers are wetted out completely before they are placed on the mold. I use a peel ply & bleeder material before putting on the bagging film. I know sometimes pull my bagging film kind of tight and that pleating the bagging film with remove some of these voids. But, I do use a very thin bagging film with lots of stretch. Visually, the bagging film looks like to conforming to all the inside corners very well.
Next question is:
At this point, what the best way to fix these voids? normally my next step is to apply 2 layers of very lightweight cloth (1.45 oz deck cloth) with the vacuum bag applied directly to the part (with bleeder material on the side) to produce a smooth glossy finish. If I use lots of pleats on the next step I am afraid I won’t get a smooth finish.
I am thinking I need to fix these voids before the next step, otherwise I won’t get the nice smooth finish at these problem areas.
Tia,
paul
