Hi all - I'm new to the composite world. I have made a couple of small parts but am still learning a lot. The question I have is how to lay out the fabric on a brake duct I am going to be making. 

I am struggling to determine if I should lay out the carbon fiber as shown in the picture below - essentially 5 separate pieces, as indicated by the different colored outlines. Or attempt to find a way to wrap the shape in fewer separate pieces. 

The piece will just be directing airflow so it will not see large loads so strength is not the utmost concern, I just want to make a solid part.

Thanks in advance for the help!

I would do that layout, but I would feed from the top of the duct. So still run your spiral around the base, but make that your vacuum manifold, and still place a port on the top of the duct but feed your resin in there. This will feed much more evenly, as well as waste less resin. On such a small part it is unlikely to make much difference, but that's my advice.

Just be sure to give yourself a good brake zone around the base so that the resin doesn't just race through the part and out the vacuum port before the part is fully infused. It will be a very quick infusion, 30 seconds to a minute sort of thing. No time to fix anything, so just be well prepared.
