Thanks Don and Bob:
I think Don is referring to the resin not the construction but
the layered stuff that Bob is describing is what I was looking for and
is normally referred to as Phenolic insulator. The cloth adds strength
to the device the same way fiberglass adds strength to the polyethylene
resins. What little research I've done since Don's message, shows that
Phenolic is a word used to describe the compound made from carbolic acid
and formaldehyde which was discovered by Dr. Leo Baekeland. I wonder if
we could make our own. (Using http://www.hotbot.com, search on
BAKELITE. Then ignore all the jewelry stuff and find the history
stuff.)
Thanks to all, John, WA5BXO

Gentlemen:
Phenolic and Bakelite ARE NOT the same.
Phenolic is laters of resin impregnated cloth bonded by resin
throughout and under pressure.
Bakelite has NO cloth or other fiber in it.
