Actually, most people who use Lexan for rotary spark gap rotors soon have 
to replace their rotors.  Lexan melts at a very low temperature, whereas 
the garolite composites (LE, CE, G-10, etc) that most people actually DO 
use have considerably higher melting temperatures.  The rotor and 
electrodes can fly apart if it melts.

McMaster-Carr has all you can think of:

I have used both Grade LE Garolite and G-10, and my personal preference is 
Grade LE.  Grade LE is a linen in an epoxy resin, machines better than 
G-10, but doesn't have quite as high material strengths as G-10.
