écritoire numérique:

I imagine a simmilar technique might be servicable for experimental
aircraft. paper fiber honeycomb is used as packing material and can
probably be had quite cheap. I was thinking, cut it to form, attach it
to the spar, drown the whole lot in epoxy. Then after it cures
filament wind it to make the skin.
More difficult than layout carbon fabric and require more tools.

I prefer the basic
1 layer bid 0°/90°,
1 layer biaxial ±45°,
1 layer bid 0°-90° in a simple wood mold


Yep. And they would need and autoclave (pressure and heat) to cure it all,
and expensive machinery to wind it with the accuracy needed to make a
reliable structure.

Filament winding is definitely not for homebuilders.
