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.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
