Information about materials is actually one of the things I find is pretty easy to locate on the internet, on places like
matweb.
It might be more useful to make a presentation on how to use the material properties available, and what they mean. I have wanted to write something such as this for a while, but have been waiting to know more about this topic (IE, I want to finish my second materials course in Uni and get some MODS behind me). If you are interested in collaborating on something, just PM me.
Another thing that might be useful would be some graphs of common FRC materials for Specific Strength vs. Cost, and other stuff like that that might aid in design decisions.
