New material from dupont might cut auto weight significantly

There's nothing like a bit of resin...found via ABG:

Quote:
DuPont has announced a new type of resin that can work as a metal substitute. The new Zytel(R) nylon resin has replaced steel in exhaust system parts on all Volkswagen vehicles built on the current Golf platform, cutting weight of the component by nearly 50 percent. The resin is used in the catalytic converter bracket to substitute a previous multi-assembled metal and rubber part, so the benefits are not only from the reduced weight but also in the ease of assembly. As stated in the press release (which you can find after the jump), this might be a small step, but it's one small way to achieve higher mileage figures.

I suppose the next question is how much will this stuff cost once it's popular? Metal is pretty cheap for these applications.

a quick google search makes it look like it's other commen use is knive and gun handles?
it seems to me that if you can replace your exaust with a high temp plastic that could be cast in to the shape insted of stamping out shapes from flat metal sheats, forming them with a die and press, crimping them together, welding them, giving them a coat of rust protection, and repeating every 5 years as they rust and fall appart... plastic exaust sounds a bit hokey, but some plastics hold up to heat rather well, and this sounds like it could be on the top of that list.
