(Automotive gear lever surround) The CF Fabric is not responding well to the contours and hole in the center. Lifting with resin etc etc.... I have tried a quick method using vacuum bagging material and the pump ... It seems to be ok so far..but haven't seen much info on doing things this way. Just curious to know if anyone else has tried this. Im still testing the best way to adapt the fabric to the part ...but it seems like a possible shortcut to covering complex parts Cover the part in CF Fabric Cover part with Resin Cover wet part with peel ply Set in bag and apply vacuum. After part has dried ... sand the marks from the peelply using thin sandpaper.... Apply normal layers of resin as finishing coats. Edited 7 Years Ago by fibernoob

I have had great results with a hand layup but decided I wanted to learn how to use a vacuum for a few parts as well. I am not trying to make a straight carbon fiber part I have done a few of those with no issue. I have been testing different things but have not had any good luck. I have a shifter panel for my mercedes, I laid the carbon fiber over it and used a glue to hold it all in place. next I used West System epoxy resin to wet everything out. Then placed a Perforated Release Film over my part and then the vacuum bagging over that. taped everything down and sucked the air out. pressure held very nicely so no issue there. However when I pulled the part out today (sat overnight) it almost looks like the release film left a layer on film on the part. I have had this happen to me twice so far. Its driving me a little crazy at this point. Can I get some pointers? I have tried some parts with various films and get the same issue and some creases too. With peel ply I get the texture on the surface but no excess resin. I have seen on some videos the use of a plastic film that stretches to the part. (I think Matthieu Libeert uses it on his videos for the mask skinning tutorials).. maybe this can be the solution.

When it was done the film came off and the part was perfect. Meanwhile I’m over here doing the same thing over and over and still have the same result. I can do thit hand lay and all that with sanding between layers but I wanted to find a better and faster method
