The Volksplanes use a composite fuel tank/forward fuselage decking originally designed for polyester resin and ordinary marine fiberglass cloth ("Alsynite" sheet still exists but now appears to be a fiberglass roofing manufacturer in Asia.) Here's the page from the now almost 50-year-old VP-2 plans:
Composite gurus, with what we know today about various resins and how they react with gasoline (including automotive fuel with potential alcohol content) what would be the best resin and fabric for this type of fuel tank today?
Bonus points if there is also a compatible sheet material readily available to use for the baffles and tank ends instead of making your own.
If the best answer is "just use polyester resin and ordinary fiberglass and slosh the tank with sealant" then that's fine, too.
If you're answer is, "Never mind composites, do it in aluminum and pop rivets," then we've already had a thread on that. ;-)
Thanks!
