I was thinking, what about tyvek for backing? It's light,thin but very dense and strong?
The heavy grade landscape cloth that you put down to keep weeds out of mulch,wonder how that would work?

In order to decide on a backing for a bow, you have to decide what you expect the backing to do, so the answer isn't a "canned" answer.
What do you want the backing to do?

Tyvec is 100 % poly fiber laid down, and compressed, and it can breath. Tough stuff. If I were to use it as a bow backing I would use Epoxy for the bond.Dave Mead used paint drop cloths for backing. I never used either. Give them a shot. You won't no till you try.

Protect the back of the bow from bumps/damage so nothing bad gets started would be the main thing.

You can use fiberglass cloth backing bonded with epoxy, or sinew. both make an excellent backing.

If you're going to go either natural or synthetic it's likely best to source well proven options.
FWIW tyvek glues best with hide glue which seems counterintuitive. Epoxy will not bond it well.

I have never tried tyvek as said above, but the fact that it breathes you would think the epoxy would work well. Have you personally tried it?

I have only backed a bow with hickory, sinew and bamboo so I am not an expert by any means.
Having made a bunch of bows, if I was going to back a bow I would choose a thicker material that would absorb the glue and become a lamination of sorts on the back of the bow.
The only Tyvek I have experience with is the suit variety, strong but very thin, I don't know about its absorption properties.
I would go with blue jean material, burlap or tight weave linin for the maximum glue absorption.

Personally if I was going to him to the trouble to apply a backing, and I wanted that backing to impart some structural integrity like the OP mentioned I wouldn't even consider anything but Bamboo, a Hickory or Maple backing strip, sinew, or glass.
Tyvek, canvas, etc. are interesting experiments, but that's about it.

I can't post any thing that has to do with fiberglass cloth backing with AE 40 smooth on on primitive archer, but when I first started making bows I used that method many times with good success. For me now it is either bamboo, Hickory , or sinew, and mostly sinew. I always have a good supply of it on hand.
