I've been using a lot of MDF lately, and it's interesting to think that it's just sawdust and glue. It makes me wonder: are there other fibers which could be used in a similar process which would yield better materials than MDF?

I think you just reinvented fiberglass and carbon fiber

Oh that's true! Is carbon fiber bonded by glue?

It's bonded by epoxy just like plywood is. Technically plywood is a composite (at least from a mechanical engineering perspective).
