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).
Ford will be the first automaker to commercially use Alcoa's tough & fast Micromill aluminum alloy process and materials, debuting on several 2016 F-150 truck components. Alcoa will also license its Micromill process and materials technology to Danieli Group.
NIST's new five-year strategic plan for its Material Measurement Laboratory lists additive manufacturing materials development as one of the main areas it will support by developing measurements, data, techniques, and models.
