We finally got a look today at the “production version” of the Chevy Volt in a grand news conference in Detroit (which I saw via the Web). The concept car—shown at the Detroit Auto Show 18 months ago—was a drop-dead beauty with edgy, angular lines. It created the kind of chill I felt when I first saw the Dodge Viper, or even the original Corvette. The production vehicle unveiled yesterday? Well, it looks kind of ordinary. In an effort to make the vehicle as aerodynamic as possible, big swooping lines are the dominant look. There’s a lot more window area. It looks more like a car for a hockey mom than Batman. The black roof that looks like polycarbonate is, however, striking. That type of feature would break ground for a mass-market car. The polycarbonate reduces weight and boosts light that could enter the car’s interior. Materials suppliers, such as Sabic Innovative Plastics, were tight-lipped today. Sabic (as GE Plastics) had provided the PC roof and composite body panels for the concept Volt. Earlier, a GM exec had told Design News in an exclusive interview that innovative materials were still very much in play for the Volt.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
