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).
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
