Thought I would start a new thread (at the risk of asking a dumb question) so as to not sidetrack some other excellent active threads on rib building, such as Brownie's Eagle thread or Pamw's M12 thread.

So, the curious question bouncing around in my noggin is:

Has anybody ever tried to invent/build a rib (non-compression or otherwise) as a substitute for wood ribs:

A) using a strong enough and light enough material that could be injection molded to produce a rib? (or is such a material not an option from an engineering standpoint)

B) produced from a buildup of composite materials that is then laser cut or water jet cut to shape?

No need to discuss stamped aluminum here...was just thinking about these 2 ideas.
