After two weak years, look for some excitement at the North American Auto Show, which opens to the press on Monday in Detroit. Audi’s new 2012 A6 will officially debut this week. From a materials’ perspective, Audi is a big believer in aluminum as a way to cut weight and boost performance. In fact, more than one-fifth of the chassis is made from aluminum, which is also used in the, doors and trunk lid. Another high-end car getting its first public showing is BMW’s 2012 1 Series M Coupe, which also make extensive use of aluminum in its chassis and various structural components.
Emphasis on lighter weight continues with the expected unveiling of Honda’s 2012 Civic concept. Design engineering of the iconic car was held up after an edict from Honda CE Takanobu Ito to make the new Civic smaller, lighter and more efficient than its predecessor. Materials’ details to come. Aluminum, again, likely will be a winner because engineering of new composites’ structures takes a few years to implement. GM, Ford, and Chrysler are working on a new composite underbody, but there likely will be little evidence at the auto show this week.
Ford is expected to show a concept that will point to the future of its SUV brand. General Motors is expected to show the Chevrolet Sonic (shown below), a new compact for the North American market that will go into production this year in Michigan. We’ll hear about the specifics this week.
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.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
