George, If I might butt in here, it would be fine for either. I have
mentioned that on anything used FWF we need to be sure the
materials won't support combustion. Carbon fiber is almost all
prepregs which are kept frozen and then heated to thermoset.
There are some new resin systems that are supposed to
self-extinguish and are so tough that the manufacturer even
RECOMENDS them as a firewall! The problem here is tooling
is expensive. You will probably end up spending 5x what you
would for your aluminum housing to get started. If you have a
good market you can get the cost down but you WON'T get
below aluminum prices on any low stress part. You can make a
stronger or lighter part, but rarely cheaper.
