Carbon Fiber Heat Shield

[justinp20012500]

Just thought I would share this with you guys.



After a long pull the truck would idle at 400 egt's. I am thinking that a heat shield will keep the hot ait coming off the top housing out of the filter. That should help cool down times.



I only have 30 or so minutes invested in the project, but it is coming along.





After the template is done I will stretch the carbon fiber over it and place it in the over @ 500* for 30 minutes. That will allow the resin to setup and hold its shape.



The fiber is like a cloth when the resin is not cooked. It is very easy to work with. It is about 70 thous. thick and super light and very stong.



I tested a piece by making a "beer can holder" and it is super strong.



After the test piece was done you could almost grab it right out of the oven. It does not retain heat at all!!!



Heres some pics.

You can cut it with a razor knife when its not cured, but when it is cured you need a cut off wheel on the grinder to cut the stuff!!

Justin we use this to lay up rock guards on our 2 stroke dirt bike pipes. I've used several different thicknesses and yes it does hold up to direct heat very well.



the expansion chamber on a dirt bike can glow red hot and these are just hose clamped straight to it. I even bury a sticker on mine on the topcoat of resin.



its a bullseye for the rocks to try and hit. After trashing several hundred dollars worth of pipes each my buddies and i decided to make it a sport with a scoring system. thus the bullseye. LOL

Hey Justin, where did you get the roll? I have always liked carbon fiber and had quite a few pieces on the last GSXR I had. I would love to get ahold of some to play with like you are doing.

any respectable boat and fiberglass repair shop will have it.

does it have good insulative properties as well? maybe wrap the hot and cold pipes with the cloth. Heck, wrap the turbine side of the turbo while you're at it!

All of our generators *Cummins 4BT* use InsulTech ( www.insultech.com ) wrap on the exhaust manifold, turbo and first few feet of the exhaust pipe. you can touch the turbo while it's running under load.

Other than protection from burns what do they use that stuff for on the generators?

I would think manifold cracking would be an issue along with longer turbo cool down times would be needed.

Interesting stuff though.

I has to be cured at or slightly under 350* or it will cathch on fire. But when it is cured I held it over a direct flame and it did nothing.



I already have header wrap on the hot pipe, I am thinking of wrapping the 5" DP as it is very close to the firewall/bellhousing.



Going in for a lower lumbar fusion tomorrow so the wrapping/testing will have to be done in a month or so

Justin, good healing wishes! hope it's going well or you.

have you seen the thread on "building a better BHAF"? is there a way to use carbon fiber to make an intake tube for that? to make a solid tube that is airtight, how do you seal the carbon fiber layers?

All is well, feeling much better. They put $14g's of titanium in my back!! I could not believe the cost.



I am not sure on how to seal it? It is very sticky when it gets to room temp. If you built up layers I am sure you could get is to seal.



I haven't got around to wrapping the DP yet. I had to move my pp/fire ringed head from my 01 to my 02. (And the twins!) I will say it again, the 24v heads are heavy mothers!!!
