He was asking about test samples, not finished product.

For a replacement for fabric skin?

So if it punches good, it's ok, right?

My only question is how much weight is added replacing fabric.

My take was that he wanted to test alternative materials, like how strong
would fiberglass have to be for putting on a wing, instead of fabric. Or,
how strong would plywood have to be to replace fabric. Add to that many
different materials, and many different applications-all over the plane.

If that is not the jist of it, so sorry, I guess.

If I am right, then I don't see how you can get around testing the
alternative material in a "similar to the real application" type of test
like I described. Creativity would need to be applied to figure out other
tests for other areas.
