Hello everyone!
I'm planing on making an intake plenum from carbon fiber and kevlar. It is for a turbocharged car, so it needs to withstand some pressure!
The boost will be under 1 bar at the moment but I'm planning on testing the part on 3 bars at least, for reassurance.
The parts will be made from heat resistant Vinylester probably, if not Epoxy resin and vacuum infusion.
I'm planning on using 3 layers of 200gr 2X2 Twill Carbon fiber and 2 or 3 layers of hybrid 164gr Plain Carbon/Kevlar, alternatly in the layers.
By that, I mean, the first layer will be Carbon fiber, then Carbon/Kevlar, then Carbon fiber etc etc.
Will these layers and fabrics will be enough? Should I add anything or change any of the layers?
Here is the 3D model of the parts in assembly.

For 2-2.5mm you will want 4 or 5 layers of 450 with a layer of 200 on either side. Alternatively 3-4...

Bit of an older post, however I could use some suggestions in materials for heat reflection. Suggestions appreciated.

So after quiet a while I found some time to continue the project! Yesterday i got the plugs from the CNC and I've already started to seal the wood so I can produce a mold. I'll get back with plenty o...

Good stuff mate, man CNC's make this game too easy! Haha. Interesting plenum design, I hadn't realised from your drawing it was such a tight area at the back. what sort of engine is it for?

Thanks Hanaldo! CNC's are really an enormous help! The intake will be put in a small Nissan engine, for some tests and the we will upscale it for (hopefully) something better. Also if anyone has...

Hanaldo this will be tested on my ''lab rat'' which is a GA series motor that I've boosted a couple of years ago. Very helpful thread for the oven! Thanks! A bit more progress now. I sealed the MDF...

Nice project, I am waiting for more photos. 1.5-2 mm will be quite enought for the wall thickness.
