How much  heat would these Porsche rotors dissipate?  What's a Porsche  
weigh?  1500 lb? How much energy would that rotor have to absorb (and  
LATER dissipate) on a typical high performance afternoon?  If the  
ceramic coating insulates the disk itself (which it must since the disk  
is Al which melts at about 900 F) then all that heat must be absorbed by  
the puck, piston, caliper and fluid.  Doable if you're dealing with a  
1500 lb [relatively] slow moving vehicle.  Still wondering' why  Boeing 
doesn't use them? 
Boeing does the math ... Jim  S.
 
Aluminum ceramic foam composite.

!500  pounds would be light even for Porsche, more like 2,000, and slow they 
don't  understand at all.


I told those Porsche people it wouldn't work. I told the formula one people  
they couldn't turn the V10s 19,000 RPM but they won't stop doing it. There are 
 no valve springs. The valves are powered by pneumatic cylinders and the cam  
shafts are programs in the engine management computer. 
 
They also use carbon pads on carbon discs which is a Violation of some  kind, 
but they won't stop doing that either.
