Hello all, Im new to the forum and new to making composite parts. I have made a couple of splitter vents for a race car of mine and now am working on brake cooling ducts for the front air dam. 

My question is how to lay up the carbon fiber to ensure a reasonable release from the mold. It currently looks like this:




I was thinking I could lay it up (after sanding and smoothing of course), as is, vacuum bag it, and essentially make it as one piece. But as I read a couple of other posts on this forum I started to second guess myself. Any suggestions from the collective?

Thanks in advance!

  

Happy to report that the new mold worked! Thanks to all for the suggestions! Used FMS, Loctite 700, and then about 9 coats of partall wax and the part slid off of the mold while I was removing the peel ply!
Bagged:


Out of the mold pre-trim:


And finally trimmed with the first one I made:



I'm pretty sure the one on the left (first one I made on the old mold) is way too resin rich. The one I de-molded yesterday seems to have a much better resin/ fiber ratio. I'm no expert though, maybe someone can look at the pictures and see if that seems right?

Again thanks for all the help!
