We're building an experimental airplane (Lancair IV-P) with carbon fiber and
Kevlar materials.  It's very expensive material and requires experience to
work with.  Also has dangers of developing severe allergies to exposure to
the epoxies used on composites.

There is no reason to justify the high expense of these materials in RSG
construction.  Good old G-10 glass laminate phenolic provides all the
strength necessary and is a much more cost effective solution.  We use G-10
in 1/2 inch thickness for most all RSG's up to 20 kVA and 5/16 inch thick
type LE phenolic for systems in the 2-4 kVA range.  No reason to spend extra
money for more exotic materials.  Save it for the most expensive heart of
the system --- the caps.
