In my country it was called prespan , it had ugly smell when burned. Fortunately it is not produced any more.
In true DIY fashion you could make the genuine stuff yourself, by soaking or painting cardboard with epoxy or gorilla glue or similar. I think that would be FR1, minus the fire retardancy of course. If you want to get fancy, use layers from an old cotton T-shirt + resin: voila, home-made FR2! For extra nice surface finish, wait until the missus is running an errand, and give it a quick press with the clothing iron!
If you can't find FR4 (or FR5), then G-10 will also do, and will be a bit sturdier than the paper or cotton based products. It comes in a lot of thicknesses, even in blocks. Machining is a bit iffy because of the embedded glass fibers, so eye protection and a mask for breathing is probably a good idea.

Both FR-1 and FR-2 are paper and phenolic resin based.
FR-3 is paper and epoxy resin, FR-4 is fiberglass cloth and epoxy resin.
