What am I doing wrong? Quick vacuum bagging test to see where bridging would occur...


But I can't get the peel ply of the back. Should I over lap the peel ply a couple centimeters past the cf?


I followed the directions on the Easycomposites tutorial. My lay up process was:
1. 200 g cf x 3 layers
2. Peel ply
3. Infusion mesh
4. Spiral tubing
5. Vacuum bag

Any help would be appreciated. Thanks!

Yeh peel ply is a prick to remove on parts after its wet out. Best thing to do is to put release film over the top of the peel ply, makes everything a lot easier. Otherwise just cut strips and tear it off in bits.

You can use perforated release film between the peel ply and mesh, the peel ply can still be difficult to remove but the mesh can be removed easily.

I recently started using a product called infuply 2. It's a flow medium glued on to perforated release film so it's one product instead of two. It leaves a softer finish than peel ply

I've read a lot about that perforated film above the peelply. 
The thing I dont get is: doenst the resin follows the easiest way? meaning throught the infusionmesh, on top of the perforated film, directly to your resin outlet to the catchpot?
causing your laminate not being fully saturated?

OT: I always trim my edges first, then I find it easier to take the peelply and pull it away in strips. or use a little bit of heat to soften the resin a bit 
Btw: whats that cloudy white shine on the bottom of your part?

No not at all. I always use perforated release film and peel ply in my infusions, because it both makes removing the consumables easier as well as assisting with degassing on the resin front. I get less pinholes in parts where I use both compared to solely peel ply.

Been there and done that. It is so hard to remove that I was actually injuring my self with over strain buy pull.
So I have a good solution that I have come up with.

First you need a 1 inch thin putty knife, sharpen it like a knife.
I use it to work my way under the peel ply to get a tab to start pulling on.
Buy yourself the biggest needle nose plyers you can get. (Mine is over a foot long and I am still looking for a 2 footer)

So this is how you use it. Lay the plyers flat on your mold and pinch the tab you have raised and simple twist exactly like you were opening a can of tuna or spam. It just rolls up like magic. Grab another tab and go again. You will be amazed and ask yourself, why didn't I think of this sooner.
Also wear some work gloves it makes it easy on the hands.

Hope this helps....no....  I know this helps!
