I have done my first steps into infusion. The quality was good, but i had a real problem. The infusion mesh-peel ply stack is impossible to be removed so the whole parts is going to live in the bin…
What’s the problem? I think that the infusion mesh was a bit resin rich from what i see. Maybe it was the curvature of the part which is not good for infusion? 
Infusion mesh is ALWAYS resin rich. That is why it is permeable to resin.
Peelply is NOT for separating infusion stacks easily. That is why perforated film is used. You definately need a perforated film to get the infusion mesh out easily.
The only other option is using a product from Fibertex, which also is easy to remove (and which is available with either infusion mesh or bleeder fused to it.)
But won’t the perforated film block the resin to go under it?
No, as it is PERFORATED. You need a film with lots of perforation, though. P, P1 or MP22 will do fine.
Do we know an approximate price for the compoflex rf fabric?

I would need to look that up. will be monday…
Thanks herman!
you dont need a release film to remove the flow medium. A good green nylon released peel ply works perfect. no reason to add another layer in my opinion, more cost, more steps. only reason to use a release film is if you dont want to use peel ply
hojo, the problem is that there is a lot of resin buildup on the infusion mesh and just because the mesh adheres to the peelply, the final system (mesh-peelply) is very stiff to remove easily from the laminate. Perhaps in a more flat part the job would be easier but in my part it’s impossible… 
I understand your problem. The solution is the proper peel ply, or release film that Herman suggested. You are probably using a “Natural” peel ply, this is not suitable.
If you want to glue something at the peel ply surface you have to be carful with coated peel plys. You can also use a perforated film between peel ply and mesh. I have never had problems with this method. In very small corners it is easier to remove than the green peel ply without a perforated film. At bigger parts the green one is perfect because it is one step less preparing the infusion.
Dependig on resin type you maybe able to salvage the part by using a heat gun to bring the resin up to it’s hdt and using a flat tool or pliers to prise/peel it off, but maybe more hassle than it’s worth.
I use an orange perf film I think its an aerovac or airtech product , can’t remember which one.
Such a shame mate. Have you tried running a stanly knife down the mesh and try pulling it off in strips any thing worth a go to save a part
if you don’t fully trust perf film, you can just put it in small areas, like just the deepest part, or edges. I did that with a 1" core block in a laminate. First time it was impossible to get off. next time I put the film ONLY around the blocks. Boom. 
If you dont use the perforated film completely you might have problems with the resinflow. It is the same problem when the perforated film is layed in two layers because than the holes are closed by the second layer.
The problem can be some pinholes in the surface where the film is partially used.
I keep myself away from knives the last days because i went to hospital and gained one stitch in my finger after playing with a knife trying to remove this stuff. :mad:
hojo, if i understood correctly, you recommend a nylon peel ply which does not adhere to the infusion mesh (flow medium)?
And where can i find this type of peel ply? Thanks!
Has anyone used the Compoflex RF product?
It sounds like a perfect solution, not only easier to remove but reducing also the time to prepare the whole setup as you put this (1 step) instead of peelply, perf.film and infusion mesh (3 steps).
The only thing making me a bit sceptical is the last commect on their website:
“Important: Due to the microporous surface of the Compoflex®, more and/or bigger valves may need to be installed depending on laminate size and thickness.”

Maybe this means that the flow is a bit restricted compared with the traditional setup?
