Those are good points. I've spent a few years repairing circuit boards made of this material and my BIG concern is how brittle the material is. Compared to the AC plywood I've used in the past PCB material just doesn't have the "give" that plywood has. In addition it seems to be heavy by comparison, but I haven't actually weighed it to see. I also agree with an earlier post the material does seem to contain more epoxy than glass.
I would worry about bonding as mentioned and the structural brittleness that I've noticed while working with the material. I would certainly build some test panels and stress them pretty hard before committing to using PCB material in my plane. If anyone tests this stuff please let us know what your results were.

If it's made from a vinal ester product, then that's what I would use to glue it to the wood. If it's made from an epoxy resin I would use an epoxy resin glue. It's not a question of the type of glue used for the wood, it has to do with the bonding properties between the glue and the PBC.

Robert, you will not believe, but it is a real country :-) Just that it is a ve-e-ery small. A exUSSR republic, have a look on the map, between Romanian and Ukraine.
