Good search term for canvas with titebond glue and other plastic matrixes. "Poor-Man's Fiberglass"
Back in the day they would use canvas covering wood for ships impregnated with paint. It's my understanding that done tight this last for decades without the wood rotting. Example,
"...The original painted canvas has been on my boat for 55 years. It's kept on the water all year long in a covered slip. I re-coat the paint every 6-8 years..."

This guy has a ton of composite manufacturing videos.
Easy composites. He's using a bunch of professional materials but you could use less costly stuff. The ideas are the same though. Here's just one of his tube videos that I mentioned.
"...Making Complex Carbon Fibre Tubes Using a Split-Mould..."

Another good one is
"Make Forged Carbon Fibre Parts Using Compression Moulding"

I believe you could use the same techniques with vacuum impregnation. Cutting cost.

Glues, titebond II and III fairly waterproof. There's an old school type glue that is super, major strong. They made boats and the WWII Mosquito aircraft was glued together with this type glue. Urea Formaldehyde glue. People are using epoxy now because it's fairly easy to use but it's in no way as good as this stuff. The basic stuff is usually called Cascamite but it goes by a ton of trade names, Semforite, Cascamite, Aerolite.
Links for water mix based glue
(these guys say waterproof). It's true many people have made boats glued only with this stuff that last. But total waterproof is...hard to judge. It appears that some manufacturers have figured a way to make the water based glues waterproof but some are only partially waterproof. No standing water. Both named Cascamite. I can not judge is the newer water mix glues are really waterproof? Old boat builders say that the old Cascamite WAS waterproof. Is the newer????

Others they call water resistant. Means no continuous water standing.

These guys say waterproof but it's still water mix based.

Now the Resorcinol Urea Formaldehyde glues are 100% waterproof and last forever but more expensive and two part with resin and activator but one of the best glues ever. You have to hunt for this stuff. It's used by the millions of tons on waterproof plywood and they
use it to bond the fibers and rubber in tires together. Tough stuff.
