Ed,
How about the printed circuit board material?
Its fiberglass and you can get it without any metal on it.
It goes by many names, FR-4, G10, NP510A NP511 etc. depending on the manufacturer.
Some manufactures will send you 18"x18" sample sheets of various thickness for evaluation.
It is easily cut and drilled with a Dremel tool.
I was condidering using it as aircraft skin material.
One of our Delta Builders actually did use this material as skins.
Jim
