Toyota Motors and Mitsubishi Motors are pushing the envelope on lightweight car design with new concept cars introduced at the Tokyo Motor Show this week. The Toyota 1/X hybrid weighs 67 per cent less than Prius due to its use of carbon fiber composites in its body, yet has more interior space. Composites previously used in auto car bodies have much heavier glass reinforcement. Carbon fiber reinforced composites, also widely used in the Boeing 787 Dreamliner, weigh 40 percent less than glass-reinforced composites. Toray, the world’s leading supplier of carbon fiber prepregs, is reportedly studying a new production plant just for automotive demand. The Mitsubishi i-MiEV (electric vehicle) uses an aluminum suspension and frame. It weighs just one-third what a steel suspension and frame weighs.
A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Plastic bearings are real and millions of them are in use doing heavy-duty jobs we used to think only metals could do. Some of Germany-based igus's bearings are traveling around the world as functional parts in a car to demonstrate what they can do.
Baxter showed off his 2.0-derived moves at ATX West this year. The big red guy still looks pretty much the same, but has some new abilities, mostly due to software. The research robot version is now being used in corporate R&D departments as a design platform.
End-production using 3D printing, including objects made of multiple materials in one pass, is getting closer to reality as we saw on the exhibit floor at the recent Pacific Design & Manufacturing Show.
