Carbon Fiber Question...
Does carbon fiber transfer heat? Such as if you had a flame on one side of a 1 ft. piece of carbon fiber would you feel heat on the other side? I am looking for all or most the characteristics of C/F heat transfer... Thanks

I'm not looking at the specs, but in general, it doesn't transfer heat nearly as well as steel or aluminum. How much heat you feel is really going to depend on the fiber pattern, the number of layers, the resin, the processing, and any coatings applied. Generally, carbon fiber resins are flammable, but fire resistant resins or processing can be used. If you want better figures, I can see about pulling out some figures for you, but I can only give you what's in the book. Let me know.

Man u must really love ur car
Who cares about heat transfer? Well I do, but not enuff to spend $$ on carbon fiber, my Vette is a street car
Carbon Fiber in my eyes is a waste of $$ unless u getting it for looks

In a nut shell:
Compression molded carbon fiber is lighter, stronger, and has a heat transfer coefficient that is 50 times lower than that of steel. Some intake shields are made from multi-layered e-glass composite material, instead of die-cut/tin-snipped aluminum sheet metal.
E-glass composite has a heat transfer coefficient that is 100 times lower than that of aluminum. This means that e-glass composite is a superior heat shield material than aluminum.
Some more reading......I like the idea of CF intake tubing;

CF does indeed transfer heat and very well at that depending on the axis and fiber type. In fact, pitch type carbon (graphite really) fibers are used for heat pipes in spacecraft. In a typical composite layup, the heat (and electrical) transfer in the direction of the fiber is good, but the through the thickness is poor because it is mostly epoxy in that axis. In our carbon fiber Hardbars that we custom make, along the bar where the braided fibers are aligned, it would be very good, but through the wall thickness it would be poor.
