Default Exciting composite materials

Don't know if this belongs in this section or not... it is news, though, and could be exciting for enthusiasts in great ways!

http://www.nsf.gov/news/special_repo.../metalfoam.jsp

In short:
An aerospace engineer named Afsaneh Rabiei created a composite metal "Foam" that's as light as aluminum, and stronger than steel... this means lighter parts that don't compromise safety or structural integrity!!!!

Other obvious uses stated in the video include prosthetics, and building materials...

The real exciting aspect, is that it's relatively cost effective! Way more so than other options, anyways.

(Admins feel free to move this if it belongs somewhere else, but "news" makes sense to me. )

Very cool video at that link. Its basically a steel/aluminum hybrid sponge. It'd be cool if Subaru was the first to use it but... well... this is Subaru we are talking about...

FHI does advanced composites work for Boeing. I think there's a good chance we'll see it on our Subarus at some point for weight savings.

Not true.

The composite foam that was created is stronger than other types of metal foams, but nowhere do they say that this material is stronger than steel or as light as aluminum.

Based on what it's made out of and how composites work it will be a great material for car bumper beams and crumple zones, but it's not going to replace the structural unibody of a car.

The video, and article both imply this, actually...

The first thing they say in the video is that she "Set out to make a material as light as aluminum and stronger than steel."

The second sentence in the article says "Afsaneh Rabiei set out to make a material as light as aluminum and stronger than stainless steel."

So they do state it... twice. Furthermore, I don't recall saying "yayyy subaru can make foam-metal FRAMES for their cars!"

Though, if they can use this material to construct the metal beams for buildings, I think it could hold it's own on something like a vehicle.

Thanks for playing, though.
