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!

  

That approach to laying down the fabric sections looks okay. You could likely do away with a separate surface piece at the horizontal base and just make the side section pieces a touch longer so that they extend down onto the base. Some diagonal cuts made at the overlapped corners should make everything look quite neat when finished

Thanks! That's a good suggestion!
