Hello all,

Can anyone tell how I can eliminate the voids I get aroundthe 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 outcompletely before they are placed on the mold. I use a peel ply & bleedermaterial before putting on the bagging film. Attached is picture one of the problemareas.

TIA,

Paul

Thanks.. I will try that.
 I know sometimes my bagging film is pulled kind of tight. 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.

I guess my next question is: Whats 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.
