I wrote last year about the potential for growing use of wood-plastic composites in car design. Now comes word that bamboo-reinforced bioplastic may make its commercial debut in the interiors of Mitsubishi’s iMiEV Sport Air electric vehicle in 2010. Mitsubishi would not confirm the roll-out date, which has been rumored on car blogs. It’s no secret though tat Mitsubishi has been working on bamboo-reinforced bioplastic for at least four years. The Japanese OEM cuts bamboos into strips, removing the joints and then crushes them. Then hot steam is used to loosen the fibers, making it fit as a reinforcement. The bamboo will be reinforcing a novel bioplastic called PBS (polybutylene succinate) resins, which is derived from succinic acid and corn starch.
According to Mitsubishi’s tests, PBS/bamboo-fiber compound achieves an estimated 50% reduction in lifecycle carbon dioxide emissions over polypropylene. VOC (volatile organic compounds) levels are also reduced drastically over processed wood hardboards (roughly 85% in testing).
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.
