I need to find an extreamly high temprature resin to be used with carbon fiber wet lay and vaccuum bagging. It is to create a bike manifold straight from the cylender head and I not sure what temprature that would be!
I doubt it could be done, but maybe some Epoxy or CF pre-preg and auto claved?
I wonder if you could add a ceramic coating to the inside of the CF to help with the extreme heat?
Try contacting some Epoxy heavy hitters like BJB Ent. in Irvine, Ca., PTM&W in Santa Fe Springs, Ca…
Im thinking that he is speaking of an intake manifold.
It would help to hear what you really mean.
You can easily find 400 degree epoxy and there is no bike I know about that has a 400 degree inlet tract tempurature.
Would carbon fiber be better than titanium for that application?
It’s for the exhaust manifold that comes out of the cylender head
Ouch. What are those temps then? I know heads can get the steel and Ti of the exhaust tubes to turn red. I really don’t know if CF can even handle constant high temps like that, nevermind the epoxy system. CF is used more downstream, like exhaust cans, since it is much cooler down there.
hit up Airtech, or check around composite world, or some other Composite journals, and their ad’s for expoy companies.
Incolnel is the best for ANY lightweight high heat exhaust manifold.
I could see making a one piece CF intake manfold, but, an exhuast manifold will be a little hard to do. Even if you could coat the internals with nickel or something like that I still dont know if it would hold up.
You mean inconel?
I just picked the common metal used in bike manifolds which is what he is replacing.
So do you think that you might be able to come as far down from the end cans to the manifold, instead of going straight from the head?
Carbon probably isn’t going to work. You will be hard pressed to find a resin that can handle those temperatures. Exhaust temperatures (on a car) can easily exceed 1200 degrees straight out of the head. Titanium is one of the best choices for a lightweight exhaust system.
Degrees F or C?
it wont work for an exhaust manifold.
1200-1500 F is normal and can exceed easily with other factors.
