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

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.
